Question

What effect does an increase in the concentration of H 3 O^ + *ions in a solution have on pH of a solution?​

Answer 1

Answer:

If the hydronium concentration increases, the pH decreases, causing the solution to become more acidic. This happens when an acid is introduced. As H+ ions dissociate from the acid and bond with water, they form hydronium ions, thus increasing the hydronium concentration of the solution
