# What is the Effect of Temperature on the Ionic, Product of Water? How Will It Change the Ph Value of a Neutral Solution? - ISC (Commerce) Class 12 - Chemistry (Theory)

ConceptChemical Kinetics Effect of Temperature on the Rate Constant of a Reaction

#### Question

What is the effect of temperature on the ionic, product of water? How will it change the pH value of a neutral solution?

#### Solution

As temperature increases, the concentration of H+ and OH increases and hence pH value decreases.

At 298 K

[H^+][OH^(-) = 10^(-14)]

∴  for neutral solution

pH = 7

and at high temperature pH will be less than 7.

Is there an error in this question or solution?
