You have an aqueous solution with a ph of 8.0. You add sodium chloride to a concentration of 1 gram per 100 milliliters. What happens to the ph?

As seen in the question above, you are manipulating a solution that has pH 8, that is, this is a basic solution. However, you decide to add sodium chloride at a concentration of 1 gram per 100 milliliters. Sodium chloride has ph7, which means that it is a neutral substance, that is, it is not a basic or acidic molecule.

Because of its neutral character and concentration, sodium chloride will not change the pH of the solution where it was added. As a result, the solution will remain at pH 8.

The pH of the aqueous solution will not be altered.

The pH scale is used to measure or tell if a solution is acidic, basic or neutral.

Acidic solutions are depicted with pH values less than 7

pH value of 7 is neutral

pH value greater than 7 is basic

Sodium chloride (NaCl) is a neutral salt as it is formed from the neutralization of a strong acid by a strong base.

Hence adding a neutral salt to the aqueous solution will neither increase it's acidity or alkalinity nor decrease it . Hence, the pH of the solution will remain the same.
