(B) In pure water,the dissociation is represented as: $2H_2O \rightleftharpoons H_3O^+ + OH^-$. Since the water is pure,$[H_3O^+] = [OH^-]$. Given that $[H_3O^+] = 10^{-6} \, mol \, L^{-1}$,it follows that $[OH^-] = 10^{-6} \, mol \, L^{-1}$. The ionic product of water is defined as $K_W = [H_3O^+][OH^-]$. Substituting the values: $K_W = (10^{-6}) \times (10^{-6}) = 10^{-12}$.
