# How is dry HCl supplied?

Aug 1, 2017

Dry $H C l$ is actually a gas........

#### Explanation:

...And it is supplied in cylinders.....because it is a polar molecule, the which we could represent as $\stackrel{\delta +}{H} - \stackrel{\delta -}{C} l$, it is effectively solvated in aqueous solutions to give discrete hydronium ions, i.e. ${H}_{3} {O}^{+}$ or ${H}_{5} {O}_{2}^{+}$ or ${H}_{7} {O}_{3}^{+}$, or even just a simple representation of ${H}^{+}$. And likewise the chloride is solvated by water molecules, $C {l}^{-}$.

Because these are CHARGED IONS, charged particles in solution, the solution will conduct electricity very effectively. On the other hand, tap water contains much smaller concentrations of ions, i.e. $C {a}^{2 +}$ and $C {l}^{-}$ and of course equilibrium quantities of ${H}_{3} {O}^{+}$ and $H {O}^{-}$, and this should be a more effective conductor than distilled water, which contains only ${H}_{3} {O}^{+}$ and $H {O}^{-}$ at small concentrations.......
