Description

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

Precursors

Reaction between zinc and ammonium sulfates

Chemical equation:

(NH4)2SO4 + ZnSO4 = (NH4)2Zn(SO4)2↓


For preparation of 100.00g of zinc-ammonium sulfate hexahydrate а 44.68g of zinc sulfate monohydrate and 32.90g 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.

Notes

This compound is a good nutrient for molds, so a little amount of food preservative like potassium sorbate might be needed. Boiling after molds appear is also effective.

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.
