Question

Ka for ethanoic acid is 1.7*10^-5 moldm-3.

Show by calculation that the initial pH in experiment B is 4.8. 

 

3 A group of students are investigating the properties of weak acids and buffer solutions. They take measurements of the pH of some solutions before and after adding an equal volume of 0.01 moldm-3 sodium hydroxide solution. Some of the students' results are shown in the table below. Experiment Original solution pH before addition pH after addition A 0.01 mol dm-3 ethanoic acid 3.4 8.2 0.1 moldm-3 ethanoic acid plus an equal volume of 0.1 mol dm-3 sodium ethanoate B 4.8 4.9 0.1 mol dm-3 sodium ethanoate 8.9 11.7 D Distilled water 7.0
