Question

How hydrogen and
hydroxyl ion concentration
gets affected in acidic and
basic solutions respectively
when (i) an acidic solution is
further diluted (ii) more
amount of base is added to a
basic solution?​

Answer 1

Answer:

A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium

Answer 2

The answers are given below

(i) In case of dilution of acidic solution, number of hydronium ions in the solution decreases. This is because the already available hydronium ions bind with hydroxyl ions of water, thus, decreasing the concentration. The pH will increase.

(ii) In the case of addition of basic solution with more base, the concentration of hydroxyl ions will increase. This is because base will provide more hydroxyl ions to the solution. The pH will further increase.
