Acidic buffer mechanism

A buffer solution is one that minimises pH changes when small amounts of an acid or a base are added to it. It does not prevent the pH from changing entirely, but it keeps the pH relatively stable.

Step-by-step lessons on AQA A Level Chemistry Buffer action (A-level only). Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
