hydraten.

/ˈhʌɪdrət/

Forms: Also hydrat.

Etymology: < Greek ὕδωρ, ὑδρ- water + -ate suffix¹ 1c. Compare French hydrate.

Chemistry.

A compound of water with another compound or an element, e.g. hydrate of chlorine. Formerly, and still by some, applied also to a hydroxide n., e.g. KOH, potassium hydrate; NH₄OH, ammonium hydrate.
