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 lesson pack introduces students to buffers, including an example in the body, plus calculation worksheet (with mark scheme) and student practical sheet to make their own buffer solution (recapping basic stoichiometry and making stock solutions) as well as comparing final pH of buffer using pH meter.

This presentation and student practical sheet looks through qualities of indicators and factors considered when selecting an appropriate indicator. The student practical sheet gets students to make ammonium sulphate using titration and methyl orange and also includes past questions with mark scheme.

This presentation and student practical sheet looks at all the possible pH curves produced from the possible strong/weak acid and base combinations. They student practical sheet runs students through adding sodium hydroxide to ethanoic acid and separately ammonia with hydrochloric acid. The practical explains mathematically why pH = pKa at the half equivalence point.

This presentation spans a series of lessons (2-3) covering the expressions of Ka and Kb and their magnitude. Slides contain modeled answers and questions for students to try, along with answer slides.

This lesson looks at salt hydrolysis and how to predict the pH of salt solutions. Presentation includes link to Wordwall task.

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)

This lesson combines Reactivity 3.1.2 and 3.1.3 to deduce formula of conjugate species and recognise them in equations for various reactions. The lesson also includes link to Wordwall task to match up conjugate pairs.

Complete lesson which explains the history of the pH scale, quick student practical comparing the use of Universal Indicator with a pH meter as well as worked examples for calculations. Student practise questions with answers are provided in the slides.

This complete lesson includes worked examples and a student practise sheet of calculations related to this lesson and R3.1.4 pH calculations.

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 complete lesson includes a presentation and student calculation worksheet with worked answers on the second page for using the pOH scale (HL).

This presentation and student practical sheet run through the basics of pH curves for strong monoprotic acids and bases. The student worksheet contains questions with worked answers attached at the end.

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 and assessed student practical sheet guide students through the use of colourimeters and application of Beer’s law to determine the rate of reaction between sodium thiosulphate and hydrochloric acid. Mark scheme included.

This lesson introduces students into how to apply the mole concept to solutions and solve a range of problems (answers included). The final slide leads onto the next planned lesson which is to create a stock solution of sodium hydroxide.

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 and student practical sheet guide students through the technique of preparing a stock solution of NaOH for titration against a primary standard (KHP).

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.

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).

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.
