A focused A Level Chemistry calculation pack covering equilibria, (Kc), (Kp), partial pressures, acid-base calculations, pH, (Ka), (pKa), buffers, indicators and titration curves.

This resource contains Topics 14 to 16 from Calculations for A Level Chemistry, with worked answers included at the back. It is intended for students who need further practice applying equilibrium ideas to concentration equilibria, gaseous equilibria, acid-base calculations and buffer questions.

The pack is suitable for students studying AQA, OCR and Edexcel A Level Chemistry, and can be used for revision, tutoring, homework, intervention lessons or independent study.

Topics included:

• Equilibria I: (Kc) and Concentration Equilibria
• Equilibria II: (Kp) and Partial Pressures
• Acids, Bases, pH and Buffers

The resource includes:

• Textbook-style explanations
• Worked examples
• Practice questions
• Worked answers for all end-of-topic questions
• Common mistake notes
• Structured calculation methods
• Equilibrium tables, (Kc) and (Kp) expressions, pH calculations and buffer methods
• An AQA-style relative atomic masses table

This pack may be useful for students who want additional practice with A Level Chemistry equilibria and acid-base calculations, particularly in topics involving (Kc), (Kp), mole fractions, partial pressures, pH, weak acids, buffers and titration curves. It can also be used by tutors and teachers as a printable resource for lessons, revision sessions or independent work.
