When titrated by a strong base such as 0.1 M NaOH solution, a solution of citric acid traverses a buffer region during which the pH of the solution climbs gradually then more steeply. From about one ...
Make an acid-base indicator. Dr Yan uses some very colourful science to find out what's acidic in his kitchen. Take 1/4 red cabbage. Finely slice the cabbage. Put all the chopped-up cabbage into a ...
