Question

Is HCl a strong base or acid?

Answer 1

Hydrochloric acid $\left(\mathrm{HCl}\right)$:

• It is a polar covalent molecule.
• It is a mineral acid of pH approximately 3.
• When $\mathrm{HCl}$ is diluted it dissociates completely into ${\mathrm{H}}^{+}$ and ${\mathrm{Cl}}^{-}$ ion.
• $\mathrm{HCl}$ can be categorized as a strong acid based on its high acid ionization value of ${\mathrm{pK}}_{\mathrm{a}}$ value.

Thus, we can say that Hydrochloric acid is a strong acid.
