Answer:

[H₃O⁺] = 1.82 x 10⁻¹⁰M

Explanation:

[H₃O⁺][OH⁻] = Kw = 1.0 x 10⁻¹⁴ = [H₃O⁺](5.5 x 10⁻⁵) => [H₃O⁺] = (1.0 x 10⁻¹⁴/5.5 x 10⁻⁵)M = 1.82 x 10⁻¹⁰M

Whats is saturated solution? what happens as a saturated solution cools?
Darina [25.2K]
A saturated solution is a solution that contains a certain amount of solute that is enough to be dissolved in the solvent. Anything above that amount will not dissolve some of the solute in the solvent. When a saturated solution is cooled, the solubility of the solute lowers making the solution supersaturated.
