How do you make a stock solution of zinc sulfate?
How do you make a stock solution of zinc sulfate?
Zinc Sulphate Solution Preparation
- Take about 100 ml of purified water in a cleaned and dried 1000 ml volumetric flask.
- Add about 28.8 gm of zinc sulfate with continues stirring.
- Add more about 700 ml of purified water, mix and allow to cool to room temperature.
- Make up the volume 1000 ml with purified water.
What is the normality of ZnSO4?
0.04
Zinc Sulfate 0.04 Normal (0.02 Molar) (Size: 500ML)
How do you make a zinc standard solution?
Zinc Standard Solution (100 ppm Zn): Dissolve 0.440 g of zinc sulfate in water containing 1 ml of 5M acetic acid and add sufficient water to produce 100.0 ml.
How do you prepare stock solution in ppm?
Use the standard dilution formula in general chemistry, i.e., Volume(1) x Concentration(1) = Volume(2) x Concentration(2). Make sure all your units are the same. Thus, you can either change 1000 ppm to ppb (1000 ppm x 1000 ppb/1ppm) = 1000000 ppb or you can change the ppb needed to ppm.
