Zinc Sulfate VS

Zinc Sulphate VS; ZnSO₄,7H₂O = 287.5

For a 0.1m solution Dissolve 29 g of zinc sulfate in sufficient water to produce 1000 mL.

Ascertain its exact concentration in the following manner. To 20 mL add 5 mL of 2m acetic acid and carry out the method for the complexometric titration of zinc, Appendix VIII D. Each mL of 0.1m disodium edetate VS is equivalent to 28.75 mg of ZnSO₄,7H₂O.
