Calculate the hydrogen-ion concentration [h+] for the aqueous solution in which [oh-] is 1 x 10-2 mol/l. is this solution acididc, basic, or neutral? show your work.

[H⁺] = 1.0 x 10⁻¹² M.

Explanation:

∵ [H⁺][OH⁻] = 10⁻¹⁴.

[OH⁻] = 1 x 10⁻² mol/L.

∴ [H⁺] =  10⁻¹⁴/[OH⁻] = (10⁻¹⁴)/(1 x 10⁻² mol/L) = 1.0 x 10⁻¹² M.

∵ pH = - log[H⁺] = - log(1.0 x 10⁻¹² M) = 12.0.

∴ The solution is basic, since pH id higher than 7 and also the  [OH⁻] > [H⁺].

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
