Question

What is ionic product constant of water? Give its value at 25°C. Will the value change if an acid, base or a salt is dissolved in water?

Answer 1

Answer:

So, it's constant at a fixed temperature. It equals 10−14 at 25 ∘C. At this temperature [H3O+]=[OH−]=10−7 mol/L. If you add acid to water, the above reaction equilibrium is displaced in order to counteract the change in the concentration of ion hydronium, i.e. the reaction is displaced to the left.
