Explain with reason...
Why aqueous HCl is more acidic than unhydrous HCl?
Asked by Ginni2k | 11 Nov, 2016, 09:43: PM
answered-by-expert Expert Answer

In aqueous medium, HCl is the strongest and anhydrous HCl is the weakest acid.

In the presence of water, HCl is entirely ionized with strong hydrogen bonding which is not in case of anhydrous HCl.
