Zinc sulfate monohydrate is a colorless and tasteless colorless or white crystal, particle or powder. We all know that any solution needs to be correctly configured. Let's take a look at the configuration standard of zinc sulfate monohydrate solution: magnesium sulfate monohydrate

1. Preparation of standard solution of zinc sulfate monohydrate: first weigh 4.3977gZnSO4 · 7H2O, dissolve it in water, transfer it to a 1L volumetric flask, and shake up at constant volume to obtain a solution containing 1mg/mL zinc.

2. This zinc containing solution does not need calibration. Generally, 4.40g is enough.

3. To calibrate the volumetric flask, it is required to weigh the standard zinc oxide for preparation: burn the zinc oxide at 800 ℃ for 1 hour, cool it, weigh it, let it dissolve in 100mL (1+100) sulfuric acid solution, transfer it to a 1L volumetric flask, and shake it up at constant volume to obtain a solution containing 1mg/mL zinc.
