The pH of a solution is defined as the negative logarithm of the hydrogen ion concentration, so: pH = -log[H+]. To determine the hydroxide ion concentration in a solution, we can use the equation Kw = [H+][OH-], where Kw is the ionization constant of water (1.0 × 10^-14 M^2). Rearranging this equation gives: [OH-] = Kw/[H+]. At pH 10, [H+] = 1.0 × 10^-10 M. Substituting this value into the equation for [OH-], we get: [OH-] = 1.0 × 10^-14 M^2 / 1.0 × 10^-10 M = 1.0 × 10^-4 M. Therefore, the correct answer is A) 1 × 10^-4 M.
