pH scale is used to determine how acidic or basic a solution is pH can be calculated using the H⁺ ion concentration pH = - log [H⁺] and if pH is known we can find out the H⁺ ion concentration [H⁺] = antilog(-pH) [H⁺] = antilog(-8.95) [H⁺] = 1.122 x 10⁻⁹ M therefore hydrogen ion concentration is 1.122 x 10⁻⁹ M
