By comparing the color of a test solution to a standard color chart, … WebThe pH range (0-14) is determined through the ion product of the water. Water dissociates to a small extent into H+and OH-ions. I = [H+] [OH-] = 10-14Molar (@ 25°C) The ion product I is strongly dependant on temperature. The temperature influences the pH measurement through four factors: temperature coefficient of the measured solution
