cryohydrate

Definitions

noun A definite mixture of ice and any crystallized salt obtained by freezing a saturated aqueous solution of the salt.

noun (Chem.) A substance, as salt, ammonium chloride, etc., which crystallizes with water of crystallization only at low temperatures, or below the freezing point of water.

noun chemistry Any salt that forms crystals containing water of crystallization only at low temperatures

The temperature of production of the cryohydrate is identical with the lowest temperature which can be produced on employing a mixture of ice and the salt as a freezing mixture or cryogen.

So long as this separation proceeds the temperature falls, but at length a point is reached at which the thermometer remains stationary until the whole is solidified, with the production of a cryohydrate.

This temperature of solidification is the same whether we start with a dilute or a saturated solution, and the composition of the cryohydrate is found to be constant.

It will be readily seen that in the formation of a cryohydrate we have an example of eutexia, since the constituents are present in such proportion as to give to the resultant compound body a minimum temperature of liquefaction.

Scientific American Supplement, No. 508, September 26, 1885 Various
a cryohydrate, [3] which possesses physical properties different from those of either the ice or the salt from which it is formed.
