Gaseous hydrogen chloride is represented as $H C l (g)$ $HCl(g)$ ......

Explanation:

In water, hydrogen chloride dissolves and ionizes to form aqueous hydrogen chloride:

$H C l (g) + H_{2} O (l) \to H_{3} O^{+} + C l^{-} (a q)$ $HCl(g) +H_2O(l) rarr H_3O^(+) + Cl^(-)(aq)$

Oxidation number results from distribution of the charge to the most electronegative atom; here, we get $H (+ I)$ $H(+I)$ and $C l (- I)$ $Cl(-I)$ .

Undergraduate treatment:

When we write $H_{3} O^{+}$ $H_3O^+$ , the $hydronium ion$ $"hydronium ion"$ , this is more of a convenience than an actual entity. When we write $H^{+}$ $H^+$ or $H_{3} O^{+}$ $H_3O^+$ we mean the $acidium$ $"acidium"$ species in water, a cluster or 3 or 4 water molecules WITH an EXTRA $H^{+}$ $H^+$ , i.e. $H_{7} O_{3}^{+}$ $H_7O_3^+$ or $H_{9} O_{4}^{+}$ $H_9O_4^+$ . The extra proton rapidly exhanges between clusters, and $H_{3} O^{+}$ $H_3O^+$ is a convenient representation.
