Webb15 okt. 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. Webb14 apr. 2024 · Boiler water chemistry needs to adhere to the following guidelines. pH level. 10 or 11. The pH level of the water needs to be kept relatively high compared to the more neutral character of water intended for other applications. A pH of 10 to 11 is ideal, while 9.5 should be viewed as a minimum.
