Vedclass · Answer

(A) The auto-ionization of water is an endothermic process: $H_2O(l) \rightleftharpoons H^{\oplus}(aq) + OH^{-}(aq)$.According to Le Chatelier's principle,as temperature $(T)$ increases,the equilibrium shifts to the right.This leads to an increase in the concentration of both $H^{\oplus}$ and $OH^{-}$ ions.Since $pOH = -\log[OH^{-}]$,an increase in $[OH^{-}]$ results in a decrease in $pOH$.

$pOH$ of water is $7.0$ at $298 \ K$. If water is heated to $350 \ K$,which of the following should be true?
