Asolution at 25 degrees celsius is 1.0 × 10–5 m h3o+. what is the concentration of oh– in this solution? 1.0 × 10–5 m oh– 1.0 × 10–14 m oh– 1.0 × 105 m oh– 1.0 × 10–9 m oh–

1.0 x 10⁻⁹ M OH⁻.

Explanation:

∵ [H₃O⁺][OH⁻] = 10⁻¹⁴.

[H₃O⁺] = 1.0 x 10⁻⁵ M.

∴ [OH⁻] = 10⁻¹⁴/[H₃O⁺] = 10⁻¹⁴/(1.0 x 10⁻⁵ M) = 1.0 x 10⁻⁹ M.

So, the right choice is: 1.0 x 10⁻⁹ M OH⁻.

it is stable as it is in group 0 which have full outer shells of electrons
