A solution of 1 g/dm 3. hydrochloric acid has a pH of 1.6. Predict its pH when it is diluted to 0.1 g/dm 3. The hydrogen ion concentration decreases by a factor of 10, so the pH increases by 1 ...
Carbon dioxide dissolves in (and reacts with) water, forming carbonic acid. As this acid forms, it breaks down (dissociates) into a hydrogen ion and a bicarbonate ion. The hydrogen ion (produced when ...
