Sagot :
Answer :The corrected answer is given below;
Weak bases react with water to form the hydroxide ion and the conjugate acid of the base. Concentration in solution does not affect whether an acid or a base is strong or weak.
The strength of an acid or a base is determined by the dissociation constant of the substance in solution.
The acid dissociation constant, Ka, is a quantitative measure of acid strength. A strong acid has a much higher Ka than a weak acid. The Ka of an acid is determined from measured titration values.
Hydrochloric acid and sulfuric acid are completely ionized in solution and are strong acids. Ethanoic acid, which is only about 1 percent ionized, is a weak acid. Magnesium hydroxide and calcium hydroxide are strong base.

Explanation:
Weak bases react with water to form the hydroxide ion and the conjugate acid of the base. Concentration in solution does not affect whether an acid or a base is strong or weak.
The strength of an acid or a base is determined by the dissociation constant (ka /Kb) of the substance in solution.
The acid dissociation constant, Ka, is a quantitative measure of acid strength. A strong acid has a much higher Ka than a weak acid. The Ka of an acid is determined from measured titration values.
Hydrochloric acid and sulfuric acid are completely ionized in solution and are strong acids. Ethanoic acid, which is only about 1 percent ionized, is a weak acid. Magnesium hydroxide and calcium hydroxide are strong base.
