Replies: Many compounds form multiple hydrates.

Another class of isolable hemithioacetals are derived from carbonyl groups that form stable hydrates.

Sublimation may more often than not form hydrates.

Caesium chloride does not form hydrates.

The salt forms crystalline hydrates, unlike the other alkali metal chlorides.
