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. Values between 0 and 7 indicate an acidic solution. WebWhile pH values have been measured as low as -3.6 [3] and as high as 17.6 [4], most solutions encountered in nature range between pH 0 to pH 14. pH is a logarithmic scale. This means that for each one-digit change in pH, the acidity …
