| Paper 1 | 2 hours | 110 | 61.1% |
| Paper 2 | 1 hour 15 minutes | 70 | 38.9% |
The questions are graded from 9 to 1. Paper 2 tends to include more questions that assess experimental design, data analysis, and evaluation of evidence, but a strong grasp of all content is needed for both examinations. Practical skills are tested entirely through written questions, with no separate practical assessment.
成绩划分为 9 至 1 等级。试卷 2 通常包含更多考察实验设计、数据分析和证据评估的题目，但两份考试都要求对所有内容有扎实的掌握。实验技能完全通过书面题目考核，没有独立的实验操作评估。
3. Topic 1: Principles of Chemistry | 主题一：化学原理
This foundation topic covers the building blocks of chemistry. You will study states of matter, kinetic theory, and the nature of elements, compounds and mixtures. Atomic structure is a key focus: you must be able to describe protons, neutrons and electrons, and deduce electronic configurations for elements up to atomic number 20.
该基础主题涵盖化学的基石。您将学习物质的状态、分子运动论以及元素、化合物和混合物的本质。原子结构是重点：您必须能够描述质子、中子和电子，并能推断原子序数 20 以内元素的电子排布。
Chemical bonding and structure are then explored in depth. This includes ionic bonding (e.g., NaCl, MgO), covalent bonding (simple molecular substances like H₂O and giant covalent structures like diamond and SiO₂), and metallic bonding. You must link bonding type to physical properties such as melting point and electrical conductivity.
接下来深入探讨化学键与结构。这包括离子键（如 NaCl、MgO）、共价键（简单分子物质如 H₂O 以及金刚石和 SiO₂ 等巨型共价结构）和金属键。您必须将键合类型与熔点、导电性等物理性质联系起来。
Electrolysis is a major practical-related area: you need to predict products at the anode and cathode for molten ionic compounds and aqueous solutions, explaining reactions in terms of ion migration and discharge. Writing correct half-equations is essential.
电解是一个与实验密切相关的重要领域：您需要预测熔融离子化合物和水溶液中阳极和阴极的产物，并从离子迁移和放电的角度解释反应。正确书写半方程式至关重要。
d, and empirical formulae are assessed frequently. You must be confident with calculations such as: number of moles = mass (g) ÷ molar mass (g/mol) or volume (dm³) concentration (mol/dm³).
定量化学贯穿始终：相对化学式质量、摩尔概念以及涉及反应质量、产率和经验式的计算经常出现。您必须对以下计算充满信心：摩尔数 = 质量 (g) ÷ 摩尔质量 (g/mol) 或 体积 (dm³) 浓度 (mol/dm³)。
4. Topic 2: Inorganic Chemistry | 主题二：无机化学
The inorganic section examines the Periodic Table in greater detail, focusing on Group 1 (alkali metals) and Group 7 (halogens). You should explain trends in reactivity down these groups by linking to atomic structure and shielding. Displacement reactions of halogens and the characteristic reactions of alkali metals with water must be known.
无机化学部分更详细地考查元素周期表，重点是第 1 族（碱金属）和第 7 族（卤素）。您应通过原子结构和屏蔽效应解释同族元素反应性的递变规律。必须掌握卤素的置换反应以及碱金属与水的特征反应。
The reactivity series of metals and the extraction of metals are covered. Understand how metals are extracted from their ores based on position in the series, with particular attention to the extraction of iron in the blast furnace and aluminium by electrolysis. The terms oxidation and reduction should be applied to these processes, using OILRIG (oxidation is loss, reduction is gain of electrons).
涵盖金属活动性顺序及其冶炼方法。理解如何根据金属在顺序中的位置从矿石中提取金属，特别关注高炉炼铁和电解法炼铝。应使用 OILRIG（氧化是失电子，还原是得电子）等术语描述这些过程中的氧化与还原。
Acids, bases and salts form a large practical topic. You need to recall definitions in terms of proton transfer, the pH scale, and methods for preparing soluble and insoluble salts. Titration calculations using concordant results are a common exam demand, often involving sulfuric acid, hydrochloric acid, and sodium hydroxide.
酸、碱和盐构成了一个庞大的实践性主题。您需要记住基于质子转移的定义、pH 标度以及制备可溶盐和不溶盐的方法。使用一致滴定结果进行滴定计算是常见的考试要求，通常涉及硫酸、盐酸和氢氧化钠。
Chemical tests for gases (H₂, O₂, CO₂, Cl₂, NH₃), for cations (flame tests and sodium hydroxide precipitation), and for anions (carbonate, sulfate, halide) must be memorised accurately. Observations such as 'limewater turns milky' or 'white precipitate insoluble in excess' are standard mark-earning phrases.
气体的检验（H₂、O₂、CO₂、Cl₂、NH₃）、阳离子检验（焰色反应和氢氧化钠沉淀法）以及阴离子检验（碳酸根、硫酸根、卤离子）必须准确记忆。“石灰水变浑浊”或“白色沉淀不溶于过量”等观察描述是标准的得分用语。
5. Topic 3: Physical Chemistry | 主题三：物理化学
e able to interpret energy level diagrams and calculate enthalpy changes using the equation q = mcΔT, then convert joules to kilojoules and relate the result to the number of moles reacted.
能量学通过放热和吸热反应以及使用简单量热法测定能量变化来引入。您必须能够解读能级图，并使用 q = mcΔT 公式计算焓变，然后将焦耳转换为千焦，并将结果与反应的摩尔数关联起来。
Rates of reaction are investigated practically and theoretically. Factors such as temperature, concentration, surface area, and catalysts affect the rate, and these effects are explained using collision theory and activation energy. Interpretation of graphs showing mass loss or volume of gas produced over time is a key skill; you should be able to calculate rate at a specific point by drawing tangents.
化学反应速率从实践和理论两个角度进行研究。温度、浓度、表面积和催化剂等因素会影响反应速率，这些效应通过碰撞理论和活化能来解释。解读显示质量损失或气体体积随时间变化的关系图是一项关键技能；您应能通过绘制切线计算某一点的反应速率。
Reversible reactions and dynamic equilibrium are studied with reference to the Haber process and the Contact process. Le Chatelier’s principle must be applied to predict the effect of changing temperature, pressure, and concentration on the position of equilibrium. The compromise conditions used in industry (e.g., 450 °C, 200 atm for the Haber process) need to be justified.
可逆反应和动态平衡的学习结合哈伯法和接触法。必须应用勒夏特列原理预测温度、压强和浓度变化对平衡位置的影响。工业上使用的折中条件（如哈伯法采用 450 °C、200 atm）需给出合理解释。
6. Topic 4: Organic Chemistry | 主题四：有机化学
Organic chemistry begins with an introduction to crude oil as a mixture of hydrocarbons and the process of fractional distillation. You must link the physical properties of fractions (boiling point, viscosity, flammability) to chain length and intermolecular forces between molecules.
有机化学首先介绍石油作为碳氢化合物的混合物以及分馏过程。必须将不同馏分的物理性质（沸点、粘度、可燃性）与碳链长度和分子间作用力联系起来。
The homologous series of alkanes and alkenes are contrasted. Alkanes undergo complete and incomplete combustion (important for environmental considerations), while alkenes serve as the starting point for many organic syntheses because of the carbon-carbon double bond. You should recognise the test for unsaturation using bromine water (orange to colourless).
烷烃和烯烃这两个同系物系列相互对比。烷烃发生完全和不完全燃烧（与环境问题密切相关），而烯烃因含有碳碳双键，是许多有机合成的起点。您应掌握使用溴水检验不饱和键的方法（橙色变为无色）。
Addition reactions of alkenes with hydrogen, steam, and halogens, as well as the production of addition polymers such as poly(ethene), are essential. You need to draw the repeating unit of a polymer from a given monomer and vice versa, and discuss the problems of polymer disposal.
烯烃与氢气、水蒸气和卤素的加成反应，以及聚（乙烯）等加成聚合物的生产是重点。需要从给定单体绘制聚合物的重复单元，反之亦然，并讨论聚合物处置带来的问题。
The syllabus also covers alcohols (ethanol), carboxylic acids (ethanoic acid), and esters. You should know that alcohols can be oxidised to carboxylic acids, and that esters are formed by the reaction of an alcohol with a carboxylic acid in the presence of an acid catalyst. Drawing and naming these simple organic compounds is regularly tested.
教学大纲还包括醇（乙醇）、羧酸（乙酸）和酯。应知道醇可被氧化成羧酸，酯是由醇和羧酸在酸催化剂存在下反应生成的。绘制和命名这些简单有机化合物是常见考点。
7. Core Practicals and Experimental Skills | 核心实验与实验技能
The specification identifies eight core practicals that students must be familiar with. These range from investigating the electrolysis of copper sulfate solution to determining the formula of magnesium oxide by combustion. Exam questions frequently ask about variables, sources of error, and improvements to the method.
课程大纲规定了学生必须熟悉的八项核心实验。从探究硫酸铜溶液的电解到通过燃烧测定氧化镁的化学式，范围广泛。考试题目经常要求说明变量、误差来源以及方法改进。
Other required practicals include: investigating temperature changes during neutralisation, investigating the effect of temperature on the rate of reaction, determining the Rf values of food colourings using paper chromatography, and carrying out an acid–alkali titration to prepare a soluble salt. For each, you should be able to identify the independent, dependent and control variables, and explain why a particular apparatus was chosen.
其他必做实验包括：探究中和反应中的温度变化、研究温度对反应速率的影响、使用纸色谱法测定食用色素的 Rf 值，以及进行酸碱滴定制备可溶盐。对于每个实验，您应能够识别自变量、因变量和控制变量，并解释为何选择特定的仪器。
The use of lab apparatus such as burettes, pipettes, gas syringes, and thermometers must be described accurately. Safety precautions (e.g., wearing goggles, handling acids carefully) and the correct method of heating are often awarded marks.
必须准确描述滴定管、移液管、气体注射器和温度计等实验器材的使用方法。防护措施（如佩戴护目镜、小心处理酸液）以及正确的加热方法常常是得分点。
8. Mathematical Requirements | 数学要求
Candidates are expected to use a range of mathematical skills. These include arithmetic and numerical computation, handling units and interconverting between cm³, dm³, and m³, using standard form and significant figures, and rearranging equations. About 20–25% of the marks across the two papers involve mathematical application.
考生需运用一系列数学技能。包括算术和数值计算、处理单位及在 cm³、dm³ 和 m³ 之间进行换算、使用科学记数法和有效数字，以及变换方程式。两份试卷中约有 20–25% 的分数涉及数学应用。
e yield, concentration of solutions, and energy change calculations using q = mcΔT. Students often lose marks by not converting units correctly or by using the wrong relative atomic mass from the Periodic Table.
常见的关键计算有：反应质量和摩尔计算、经验式和分子式的确定、产率百分比、溶液浓度，以及使用 q = mcΔT 进行能量变化计算。学生常因单位换算错误或使用了周期表中错误的相对原子质量而丢分。
9. Common Misconceptions and Exam Tips | 常见误区与应试技巧
One widespread misconception is confusing intermolecular forces with covalent bonds. When explaining melting or boiling, you are breaking intermolecular forces (not covalent bonds), except in giant covalent substances. Another area is the difference between a concentrated acid and a strong acid: concentration is about moles per unit volume, while strength refers to the degree of ionisation in aqueous solution.
一个普遍误区是将分子间作用力与共价键混淆。解释熔化或沸腾过程时，您破坏的是分子间作用力（而非共价键），巨型共价物质除外。另一个易错点是浓酸和强酸的区别：浓度指单位体积内的摩尔数，而强度则指在水溶液中的电离程度。
When writing ionic half-equations, ensure charges and atoms are balanced. In organic chemistry, many students forget that a functional group must be shown in a displayed formula (e.g., the COOH group). In equilibrium questions, always state the direction of shift "to the left" or "to the right" and then link to observable colour or yield change.
书写离子半方程式时，确保电荷和原子均配平。在有机化学中，许多学生忘记在展示式中标出官能团（如 COOH 基团）。在平衡类题目中，务必说明平衡“向左”或“向右”移动，然后联系到可观察的颜色或产率变化。
Exam mistakes often arise from not reading the question command word. 'Describe' expects factual statements; 'Explain' requires reasoning using scientific principles; 'Evaluate' asks for both arguments and a concluding judgement. Time management is critical, particularly in Paper 1 which has more extended-response questions.
考试中常因没看清指令词而失分。“描述”要求陈述事实；“解释”需要用科学原理进行推理；“评估”则要求给出论据并作出总结性判断。时间管理至关重要，尤其是在扩展回答题较多的试卷 1 中。
10. Revision Strategies | 复习策略
Effective revision begins with a topic checklist from the specification. Use the Edexcel syllabus document to traffic-light your knowledge. Active recall through flashcards for definitions, chemical tests, and equations is highly effective, as is completing past paper questions under timed conditions.
高效复习应从根据课程大纲制作主题清单开始。使用 Edexcel 教学大纲文件，用交通灯法标示自己的掌握程度。通过闪卡主动回忆定义、化学检验和方程式非常有效，在计时条件下完成历年真题也同样重要。
Mind maps can help link concepts, for example connecting bonding structure to physical properties, or linking organic functional groups to reactions and uses. Focus on core practicals by writing out the method, variables, expected results, and improvements for each. Finally, review calculated examples and ensure you are comfortable with the key mathematical steps without a calculator check until the end.
思维导图有助于关联概念，例如将键合结构连接至物理性质，或将有机官能团联系到反应及其用途。重点关注核心实验，写出每个实验的方法、变量、预期结果和改进措施。最后，复习计算示例，确保您对关键数学步骤感到得心应手，直到最后一步才用计算器核验。
