Answer: A. Hydrochloric acid (HCl)
Explanation:
Strong acid is defined as the acid which completely dissociates when dissolved in water. They have low pH. These releases [tex]H^+[/tex] ions in their aqueous states.
[tex]HCl(aq.)\rightarrow H^+(aq.)+Cl^-(aq.)[/tex]
Weak acid is defined as the acid which does not completely dissociates when dissolved in water. They have high pH. These releases [tex]H^+[/tex] ions in their aqueous states.
[tex]CH_3COOH\rightleftarrow CH_3COO^-+H^+[/tex]
Weak bases are defined as the basis which does not completely dissociates when dissolved in water. They have low pH. These releases [tex]OH^-[/tex] ions in their aqueous states.
[tex]NaOH\rightarrow Na^++OH^-[/tex]
[tex]NaHCO_3[/tex] is a salt formed by combination of [tex]H_2CO_3[/tex] and [tex]NaOH[/tex].
As, this compound is completely dissociating into its ions and also releasing [tex]H^+[/tex] ions. Hence, [tex]HCl[/tex] is considered as a strong acid.
