Answer:
A the pH of acids increases and the pH of the bases decreases and both go towards 7 or neutral. this is why if you spill an acid or base on your skin or clothes, you flush them with excess water
Explanation:
How does the PH value of a solution change when water is added
A the pH of acids increases and the pH of the bases decreases
B the pH of acids decreases and the pH of bases increases
C the pH of both acids and bases decreases
D the pH of both acids and bases increases
Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution.
When an acidic solution is diluted with water the concentration of H+ ions decreases and the pH of the solution increases towards 7.
Similarly, when a base is diluted with water the concentration of OH- ions decreases. This causes the pH of the basei to fall towards 7, making the solution less basic as more water is added.
