A student prepares a buffer solution by mixing equal volumes of 0.10 mol dm⁻³ ethanoic acid and 0.10 mol dm⁻³ sodium ethanoate.
Compare the buffer solution with pure water in terms of how each responds to the addition of a small amount of strong acid.
In your answer, include:
- a definition of a buffer solution
- an equation to show how the buffer controls pH when acid is added
- an explanation of why the pH change is small
