Vedclass · Answer

(B) In an aqueous solution at $25^{\circ}C$,the product of the concentrations of hydronium ions and hydroxide ions is constant,given by $[H_3O^+][OH^-] = 10^{-14}$.For a neutral solution,$[H_3O^+] = [OH^-] = 10^{-7} \; M$.For a basic solution,the concentration of hydroxide ions is greater than the concentration of hydronium ions,meaning $[OH^-] > [H_3O^+]$.Since $[H_3O^+][OH^-] = 10^{-14}$,if $[OH^-] > 10^{-7} \; M$,then $[H_3O^+] Therefore,for a basic solution,the correct relation is $[OH^-] > 10^{-7} \; M$.
