WebOct 15, 2024 · When the pH value is a whole number (e.g. pH 7), the number is equal to the negative exponent of the H + ion concentration. (8.2) pH value = X [ H +] = 10 − X M. So for pH 7, the H + ion concentration is 10 -7 M. The pH values of everyday chemicals typically range from pH 0 to pH 14.
