OCR A Level Chemistry Titrations Bundle: AS + A2 Workbooks with Mark Schemes

Full description:

Every titration type on the OCR A specification, from the first AS burette reading to the 8-mark back titration + redox calculation in Year 13, in two step-by-step workbooks.

• Titrations 1 (AS, Year 12, 41 pages): practical method (PAG 2), burette readings, concordant titres, significant figures, percentage uncertainty, n = cV, mole ratios, scaling up, Mr, x and % purity, and practical errors
• Titrations 2 (A2, Year 13, 50 pages): back titrations, redox equations, MnO₄⁻ and iodine–thiosulfate titrations, unfamiliar redox titrations, back titration + redox, pH curves, indicators, Ka from graphs and six-mark questions

Every skill follows the same pattern: Learn it (rule, common mistake, examiner tip), See it (worked example) and Try it(OCR-style questions with marks). Each book ends with a 50-mark exam paper and full OCR-style mark schemes.

Use it across Years 12 and 13, or give Year 13 students both books to fill gaps before the exams.

What's inside: 2 workbooks (91 pages), 20 skills, 74 practice questions, two 50-mark exam papers, answers and mark schemes, skills trackers.

Licence: single user. Written for OCR A H432; not endorsed by OCR.
