This lesson focuses on why and how titration is used as well as a 5 step process students can follow to scaffold their calculations. Resource include presentation and worksheet with answers.

This lesson includes the presentation and student practical sheet to run through the various methods for determining if an acid is strong or weak. The document includes past paper questions with their mark schemes.

This presentation and student practical sheet introduces the Arrhenius Equation and how it can be modified to determine activation energy (Ea) for a simple experiment using UV beads. The advantage of this task is it is far more straightforward for students to complete compared to more complex class practicals such as the reaction between bromate and bromide ions or the iodine clock reaction. There is also much less prep and tidying! This activity includes a spreadsheet of sample data and calculation which can be shared with students.

This presentation works through with examples and questions a series of problems linked to determining pH, Ka, pKa, Kb, and pOH for students at higher level (IB), but would be suitable for A Level students. Solutions and answers are in the notes section of the presentation.

This presentation and student practical sheet guide students through preparing a stock solution of hydrolysed aspirin which is then titrated against HCl to enable moles of aspirin to be determined.

This lesson pack would be suitable over a 2-3 series and guides students through the preparation of Epsom salt (magnesium sulphate) and analysis to determine its water of crystallisation. This pack includes presentation, student practical sheet plus practical assessment paper with mark scheme included.

This presentation works through how to determine empirical formula from percentage composition or mass, determining molecular formula from empirical formula and Mr. It also includes student practical sheet to determine empirical formula of magnesium oxide with a focus on error and uncertainty in processing answers.

This complete workbook for structure 1 provides a comprehensive blend of class tasks, practical experiments, and exam-style questions to reinforce learning and ensure thorough preparation for assessments. The workbook includes key content aligned with the IB Chemistry syllabus, ensuring that students can build a strong foundation in this unit.

This is a complete bundle of resources including presentations, student work sheets and students practical sheets to meet the new IB Reactivity 3.1 syllabus. Calculations in presentations and worksheets have worked answers provided. The resources here may also be appropriate for other exam boards and includes the following sequence of lessons: Development of acid/base theory Reactions of acids and bases Conjugates pH scale and pH calculations Using the ionic product of water (Kw) Strong and weak acids pH curves (SL & HL) pOH scale and calculations Using Ka, pKa, Kb and pKb pH of salt solutions Indicators Buffers (including calculations)

All empirical formula resources which cover: How to calculate empirical formula from mass or percentage composition How to calculate empirical formula from experimental data and associated sources of error and calculating uncertainty Water of crystallisation - preparing and analysing magnesium sulphate (includes a 20 mark formative assessment with mark scheme).
