MISSION MEDIA HOME THEORY We know the number of hydronium ions determines the acidity of a solution and that is the measure of the acidity. You measured a pH of 7 in a solution with 10-7 ionized water molecules. Create a formula to calculate the pH depending on the H concentration (H+)! a) pH = -log (H+) b) pH = log (1 x 107) C)...
