Question

$HCl$ acid is

• A. Monobasic
• B. Dibasic
• C. Tribasic
• D. All the above

Answer 1

The correct option is A

Monobasic

$HCl$ dissociates in an aqueous solution producing $1H^{+}$ per molecule of the acid.

$HCl+\stackrel{H_{2}O}{⟶}{H}^{+}+C{l}^{-}$

$H^{+}+H_{2}O⟶H_3{O}^{+}$

And hence $HCl$ is a monobasic acid.
