A solution of hydrochloric acid of concentration 0.001 mol dm-3 has a pH value of 3. Suggest, giving a reason, the pH of the following solutions of acids:
A solution of 0.01 mol dm-3 ethanoic acid has a concentration of hydrogen ion of 1 x 10-4 mol dm-3. Determine the percentage of ethanoic acid molecules that have dissociated.
Two separate titrations are carried out using 25.00 cm3 of 0.01 mol dm-3 solutions of hydrochloric acid followed by ethanoic acid, against 0.01 mol dm-3 sodium hydroxide.
State what difference(s) would be observed in the two titrations.
Marble chips are added separately to solutions of the same concentration of ethanoic acid and hydrochloric acid. State one similarity and one difference you would expect to observe in the reactions.
