Vedclass · Answer

(A) The $pH$ of a solution is related to the concentration of $[H^+]$ ions by the formula $pH = -\log[H^+]$.In an aqueous solution,the product of $[H^+]$ and $[OH^-]$ is constant at a given temperature,represented by the ion product of water,$K_w = [H^+][OH^-] = 10^{-14}$.If the concentration of $[OH^-]$ decreases,the concentration of $[H^+]$ must increase to maintain the constant $K_w$.As the concentration of $[H^+]$ increases,the $pH$ value decreases because $pH$ is inversely proportional to the logarithm of $[H^+]$ concentration.Therefore,a decrease in $[OH^-]$ concentration leads to a decrease in $pH$.

In a basic aqueous solution,if the concentration of $[OH^-]$ decreases,what happens to the $pH$?
