Complete the sentence. When an acid is added to water, hydroxide ions __________.
kenny6666 [7]

Answer:

The hydroxide ions decrease.

Explanation:

I got it right on the quiz. This is what I saw. Read this, "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."

Hope this helps! Tell me if this is wrong just incase.
