Question

Is $\mathrm{HCl}$ a stronger acid than $\mathrm{HF}$?

Answer 1

$\mathrm{HCl}$ acid is not stronger than $\mathrm{HF}$, The ability of an acid to liberate its ${\mathrm{H}}^{+}$ ions is measured by its acid strength, Strong acids are defined as acids that are completely ionized into their ions, A strong acid ionizes completely in solution, whereas a weak acid forms only a small amount of ${\mathrm{H}}^{+}$.

1. The strength of the $\mathrm{H}–\mathrm{A}$ bond determines the acid.
2. The less energy needed to break a bond, the weaker it is.
3. That's why the acid is powerful.
4. The only hydrohalic acid other than$\mathrm{HF}$ is not strong.
5. Aqueous solution ionized by$\mathrm{HF}$,$HF+H_{2}O\stackrel{}{\to }{H}_3{O}^{+}+F^{-}$.,
6. The ions ${\mathbf{H}}_{\mathbf{3}}{\mathbf{O}}^{\mathbf{+}}$ $\mathrm{F}$ are attracted to each other and form a strong bond$\mathrm{HF}$, The strength of $\mathrm{HF}$ water is limited because the hydronium ion bonded to the fluoride ion is not free to act as an acid.
7. $\mathrm{HCl}$ is dissolved in water,$\mathrm{HCl}\left(\mathrm{aq}\right),{\mathrm{H}}^{+}\left(\mathrm{aq}\right),\mathrm{and}\mathrm{Cl}\left(\mathrm{aq}\right)$ ions are strong acid is one that completely dissociates into ions.
8. Since $\mathrm{HCl}$ dissociates completely to form many ${\mathbf{H}}^{\mathbf{+}}$ ions in water, it is a strong acid, unlike $\mathrm{HF}$ attract to each other and creates a light acid.

Hence,$\mathrm{HCl}$ acid is not stronger than $\mathrm{HF}$.
