A "Google Search" (<URL:http://www.google.com>) for hydrochlorate
led me to : Websters Revised Unabridged Dictionary 1913.
(<URL:http://machaut.uchicago.edu/cgi-bin/WEBSTER.page.sh?PAGE=716>.)
and provided the following definitions:

Hydrochlorate
(Hy`dro*chlo"rate) n. (Chem.) Same as Hydrochloride.

Hydrochloride
(Hy`dro*chlo"ride) n. (Chem.) A compound of hydrochloric acid with a
base; / distinguished from a chloride, where only chlorine unites
with the base.

So, it looks like hydrochlorate of ammonia would be ammonium
chloride.  Handy to know about Webster's 1913!
