9. Investigate how pH changes for titrations of: weak acid vs. strong base

To investigate how pH changes when a weak acid reacts with a strong base. Requirements  two 50 cm3 burettes two funnels 100 cm3 beaker deionised (or distilled) water in a wash bottle stand and clamp pH meter/probe 100 mol dm–3 sodium hydroxide solution 100 mol dm–3 ethanoic acid solution standard pH buffer solutions at pH 4.00, 00 and 9.20 stirring
