Physical state of acids when they are ionized
« on: May 03, 2014, 02:25:00 PM »
HCl(l) + H2O  :rarrow: H+(aq) + Cl-(aq)

or is it

HCl(g)+ H2O  :rarrow: H+(aq) + Cl-(aq)

If HCL is liquid is it dil. or conc.  ??

Check what is the boiling point of HCl waterfree. In which status would it be under normal condition and if you you had liquid condition what happend to water in this case.

Ionization does not occur in the gas phase (except under very special conditions).

If ionization is occurring, the acid must have come to the liquid phase somehow.

Can you think how?

HCl is a gas at STP, to make it liquid you need either low temp (boiling point around -85 °C) or high pressure. But even then it is hardly an acid, as HCl molecule is covalent. It requires water to dissociate and produce H+.
