There is a formula to find pH pH = -log [H + ] or pH = -log [ H 3 O + ]

pH. pH. There is a formula to find pH pH = -log [H + ] or pH = -log [ H 3 O + ] (brackets around a substance means that substances concentration in molarity) To find the pH you need to H + concentration Most of the time you will get an acids concentration. Finding the [H + ].
