Q
what is a buffer solution?
A
solutions that resist the change in pH on the adding of small amounts of acid or base
2
Q
what does an acid buffer solution contain?
A
mixture of weak acid and conjugate base
3
Q
what does a basic solution buffer contain?

what is an example of an acid buffer mixture?
A
ethanoic acid and sodium ethanoate
5
Q
what are indicators?
A
weak acids or bases that are able to give a measure of the pH of solution by their colour
6
Q
what is an equivalence point?
A
the point in a titration that where the amount of titrant added is enough to neutralise the solution completely
