STANDARD METHODS FOR THE EXAMINATION OF WATER AND WASTEWATER
STANDARD METHODS FOR THE EXAMINATION OF WATER AND WASTEWATER

The ,color, value of water is extremely pH-dependent and invariably increases as the pH of the water is raised. When reporting a ,color, value, specify the pH at which ,color, is determined. For research purposes or when ,color, values are to be compared among laboratories, determine the ,color, response of a given water over a wide range of pH values. 3. d.
