desiccator's Usage Examples:

It crystallizes in prisms which melt at 39° C. A chloral hydroxylamine, CC1 3 [[Choh Nhoh]], melting at 98° C. is obtained by allowing a mixture of one molecular proportion of chloral hydrate with two molecular proportions of hydroxylamine hydrochloride and one of sodium carbonate to stand for some time in a desiccator.


Liquids are dried either by means of the desiccator, or, as is more usual, by shaking with a substance which removes the water.


The process may be accelerated by exhausting the desiccator; this so-called vacuum desiccation is especially suitable for the concentration of aqueous solutions of readily decomposable substances.


Otherwise a desiccator must be employed; this is essentially a closed vessel in which a hygroscopic substance is placed together with the substance to be dried.


desiccator used rather than drying the crystals in an oven?


Concentration of the aqueous solution in a desiccator gives a deposit of crystals of a very deliquescent salt, H21n2(S04)4.8H20.


By evaporating in vacuo the solution obtained by dissolving iron in hydrochloric acid, there results bluish, monoclinic crystals of FeCl24H20, which deliquesce, turning greenish, on exposure to air, and effloresce in a desiccator.


The green salt appears to dissociate in aqueous solution into two ions, namely CrC1 2 (OH 2) 4 and one chlorine ion, since practically only one-third of the chlorine is precipitated by silver nitrate solution at o° C. Two of the six water molecules are easily removed in a desiccator, and the salt formed, CrC13.4H20, resembles the original salt in properties, only one-third of the chlorine being precipitated by silver nitrate.

After ignition, it is allowed to cool in a desiccator and then weighed.
