Including: acid-base theories; strong and weak acids and bases; an introduction to \(pH\), \(K_w\) and \(pK_w\), \(K_a\) and \(pK_a\), \(K_b\) and \(pK_b\); buffer solutions; pH curves and indicators.
- 2. Strong and Weak Acids
- This page explains the terms strong and weak as applied to acids. As a part of this it defines and explains what is meant by pH, Ka and pKa.
- 3. The Ionic Product for Water
- This page explains what is meant by the ionic product for water. It looks at how the ionic product varies with temperature, and how that determines the pH of pure water at different temperatures.
- 4. Strong and Weak Bases
- This page explains the terms strong and weak as applied to bases. As a part of this it defines and explains Kb and pKb. The usual way of comparing the strengths of bases is to see how readily they produce hydroxide ions in solution. This may be because they already contain hydroxide ions, or because they take hydrogen ions from water molecules to produce hydroxide ions.
- 6. Acid-Base Indicators
- This page describes how simple acid-base indicators work, and how to choose the right one for a particular titration.
- 7. Buffer Solutions
- This page describes simple acidic and alkaline buffer solutions and explains how they work.
