Which statement is true about hcl? (5 points) select one: a. it is a salt because it increases the concentration of metallic ions. b. it is a salt because it is formed by the reaction of an acid and a base. c. it is an acid because it increases the concentration of hydroxyl ions. d. it is an acid because it increases the concentration of hydronium ions.

ANSWER

It is an acid because it increases the concentration of hydronium ions.

HCl is an acid. When HCl is added into water, it undergoes the following dissociation:

  HCl + H₂O(l) → H₃O⁺(aq) + Cl⁻(aq).

The Arrhenius definition defines acids as subtances that release H⁺(aq) when put in water. This H⁺(aq) ions that HCl releases reacts with water to form H₃O (hydronium), leading to an increase in concentration of H₃O.
