Zinc sulphate synthesis

2synthesis methods
Zinc sulfate is produced from side streams of electrolytic zinc manufacture. The main source of secondary zinc for zinc sulfate production is galvanizer residues. ZnSO4 is available as the mono-, hexa- and heptahydrates with zinc contents of 36%, 24%, and 22%, respectively.

Reaction Conditions:

with sodium hydroxide

Steps:

Sample 116

Sample 116
An aqueous composition was prepared as follows.
A glass beaker was placed on a scale, and then, 4.5 g (12.44 mmol) of 25% sodium chlorite solution was placed in the beaker.
Next, 94.3 ml of deionized water was added to the beaker.
After adding the water, a magnetic stirrer was added to the beaker and the contents of the beaker were stirred.
Next, 1 g (12.5 mmol) of the 50% sodium hydroxide solution was added to the beaker, and the contents of the beaker were further stirred.
Next, 0.27 g (1.7 mmol) of anhydrous zinc sulfate (obtained from VWR) was added to the beaker and the contents were mixed to produce an aqueous composition.
The composition included white crystals at the time of preparation.
