Description

Inorganic compound, double salt of transitional metal manganese, ammonium ion and inorganic sulfuric acid. From water solutions crystallizes as hexahydrate.

Precursors

Reaction between manganese(II) and ammonium sulfates

Chemical equation:

(NH4)2SO4 + MnSO4 = (NH4)2Mn(SO4)2↓


For preparation of 100.00g of manganese(II)-ammonium sulfate hexahydrate а 43.20g of manganese(II) sulfate monohydrate and 33.78g of ammonium sulfate is required.

Dissolve compounds in hot water apart and then mix solutions into one container with intense stirring. Cooling or evaporation of a solution will cause double salt crystallyzation. Filter precipitate and wash it wish small amount of ethanol or acetone, then filter the solution and use it for crystal growing.

Due to the high solubility of the product and the heat generated during dissolution, compounds should be added carefully and less amount of water is recommended.

Storage conditions

Store in its original form or under several layers of varnish at average humidity and room temperature. Do not store in matchboxes or cotton wool and do not heat.

Solubility

Very highly soluble in water. Insoluble in ethanol and acetone.
