Explain what would happen to the pH of a solution of aqueous hydrochloric acid if you add water.
pH is a measure of the concentration of H+ ions contained within a given volume of a solution. Adding water, without increasing the amount of hydrochloric acid particles within the solution, increases the volume without increasing the amount of solute particles dissolved within the solution. Therefore, the concentration of H+ ions ions decreases which causes the pH to increase.
