# How does hydrogen chloride behave in aqueous solution?

The hydrogen chloride molecule hydrolyzes in water to give, formally, ${H}_{3} {O}^{+}$ and $C {l}^{-} \left(a q\right)$ ions.
Alternatively, I could have proposed that hydrolysis gives ${H}^{+} \left(a q\right)$ and $C {l}^{-} \left(a q\right)$ ions. In water these ions are solvated, or $\text{aquated}$ by several water molecules. And so the electron devolves to an electronegative atom that could be solvated by water molecules.
