• # question_answer What is the effect of temperature on ionic product of water and why?

Ionic product of water $({{K}_{w}})$ increases with increase of temperature because ${{K}_{w}}\,=[{{H}_{3}}{{O}^{+}}]\,[O{{H}^{-}}]$ and dissociation of ${{H}_{2}}O$ to give ${{H}_{3}}{{O}^{+}}$ and $O{{H}^{-}}$increases with increase of temperature.
