monohydrate

/ ˌmɒnəʊˈhaɪdreɪt /

a hydrate, such as ferrous sulphate monohydrate, FeSO 4 .H 2 O, containing one molecule of water per molecule of the compound

First recorded in 1850–55; mono- + hydrate

According to this chemist, the true monohydrate readily freezes in cold weather, and remains solid up to 51 Fahr.

This is, therefore, the transition temperature for the trihydrate and monohydrate.

At temperatures above 0, barium acetate can form two stable hydrates, a trihydrate and a monohydrate.

The curve of the latter hydrate extends to 175.5 (L), and is then succeeded by the curve for the monohydrate.

Before the melting point of the monohydrate is reached, two liquid phases are formed, as in the case of sulphur dioxide and water.
