Question

When an acid is mixed with water, what happens to:- a) The conc. of hydronium ions per unit volume. b) The conc. of hydroxide ions per unit volume.

Answer 1

a answer is correct

Answer 2

in first case the concentration of hydronium Ion increases per unit volume as acid H+ but the Hydroxide Ion per unit volume decreases as the conjugate base of the acid will take some volume and as the H plus will increase therefore hydroxide and will decrease
