Answer:

By adding acid to hydrogencarbonate you create a large concentration of CO2 in solution causing the solution to be highly supersaturated. This keeps the pH down as CO2 is in equilibrium with carbonic acid. During the day long mixing the excess CO2 strips off and as acid leaves the solution the pH increases.

Hope it helps

A solution with a pH of 8 will have its pH reduced with the addition of hydrochloric acid.

What is pH?

It is the degree of acidity or alkalinity of solutions.

pH ranges from 0 to 14 with 7 being a neutral pH. Any pH below 7 is acidic while above 7 is basic.

Thus, a pH of 8 is basic and the addition of hydrochloric acid will reduce it towards 7 or even below it.
