Vedclass · Answer

(A) The $pH$ of a solution is defined as $pH = -\log[H^+]$.For a $KOH$ solution,the ionic product of water $(K_w = [H^+][OH^-])$ increases with an increase in temperature.As $K_w$ increases,the concentration of $[H^+]$ increases,which leads to a decrease in the $pH$ value.Alternatively,$pH + pOH = pK_w$. As temperature increases,$pK_w$ decreases,and since $pOH$ is relatively stable for a strong base,$pH$ must decrease.
