Question

What is the effect of temperature on ionic product of water?

Answer 1

It will do that by absorbing the extra heat. That means that the forward reaction will be favoured, and more hydrogen ions and hydroxide ions will be formed. The effect of that is to increase the value of Kw as temperature increases. ... You can see that the pH of pure water falls as the temperature increases.

Answer 2

An increase in a solution’s temperature will cause a decrease in viscosity and increase in the mobility of the ions in the solution. An increase in temperature may also cause an increase in number of ions in the solution due to the dissociation of the molecules. As a result, there will be an increase in conductivity of the solution.
