A-level chemistry: Acids and bases

A complete unit of work, with work book, sheets and powerpoints, covering the Acid & Bases content for A-level chemistry. Reviews year 12 content, calculates pH, use the acid dissociation constant (Ka) to calculate pH of weak acids. All activities are scaffolded to allow students to progress at their own pace. This workbook would be ideal for use in class, as a homework or as a revision aid.
Written for the OCR specification but also covering aspects common to all courses this 38 page .pdf booklet covers:

• key knowledge from year 12.
• An explanation of basicity.
• An introduction to the Bronsted-Lowry definition of acids and bases
• Conjugate acid/base pairs
• Calculating pH and hydrogen ion concentration
• Determining Ka and calculating pKa
• Using pKa as a measure of the strength of weak acids
• Calculating acid quantities using the Ka equation
• Using Kw to calculate the pH of a base
• Calculating the pH of water at different temperatures

Explanations are reinforced with 14 exercises for students to complete as well as summary tasks pitched at a level appropriate for year 13 chemistry students.
Answers are provided in a separate document.

This resource contains a pdf copy of the workbook, a word copy of the workbook and a pdf scan of a completed booklet with all answers. Also inludes powerpoints and additional sheets for teaching in class.
