Detailed explanation-1: -This compound only partly dissociates in aqueous solutions. Furthermore, the conjugate base of carbonic acid, which is the bicarbonate ion, is a relatively good base. These are the reasons why carbonic acid is classified as a weak acid rather than a strong acid.
Detailed explanation-2: -The bicarbonate ion (HCO3-) is a weak base and also a weak acid. Likewise, the carbonate ion is a weak base. It is unfortunate that the terms “weak” and “strong” are used with two related but distinct meanings. HCl is a strong acid because it is completely ionized in solution into H+ and Cl-ions.
Detailed explanation-3: -HCO3 is a base managed by the kidneys. As HCO3 increases, the blood becomes more alkaline and the pH increases. As HCO3 decreases, the blood becomes more acidic and the pH decreases.
