Description

Inorganic compound, double salt of transitional metal zinc, alkaline metal sodium and inorganic sulfuric acid. From water solutions crystallizes as tetrahydrate.

Minerals

Occurs in nature as changoite mineral.

Precursors

Reaction between zinc and sodium sulfates

Chemical equation:

Na2SO4 + ZnSO4 = Na2Zn(SO4)2↓


For preparation of 100.00g of zinc-sodium sulfate tetrahydrate а 76.57g of zinc sulfate heptahydrate and 85.79g of sodium sulfate decahydrate 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.

Influence of pH level

Addition of ~0.2-0.5g of baking soda per 100g of solution leads to growing more transparent crystals, as impurities form a precipitate.

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.
