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

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