Answer:
It lowers the pH.
Explanation:
pH (or hydrogen potential) is a value that indicates the concentration of hydrogen ions (H⁺), which shows whether a substance is acidic, neutral or alkaline.
These values generally range from 0 to 14, with substances having a pH of 0 to 7 considered acidic, those with 7 considered neutral, and those having values above 7 are alkaline.
Thus, the lower the pH of a substance, the higher the concentration of ions H⁺ and therefore the more acidic it will be. So, the addition of an acidic substance to a compound implies a reduction in pH.
