How to Configure Magnesium Sulfate Septahydrate Solution

Magnesium sulfate heptahydrate is a colorless, tasteless, colorless or white crystal, particle or powder. We all know that any solution needs to be configured. So let's look at the configuration standard of magnesium sulfate heptahydrate solution.

1. Preparation of standard solution of magnesium sulfate heptahydrate: First, 4.3977MgSO4.7H2O was weighed, dissolved in water, transferred to a L flask, and shaken uniformly at constant volume. The solution containing 1 mg/mL of magnesium was obtained.

2. This magnesium-containing solution does not need to be calibrated. It is generally called 4.40g.

3. The calibration capacity bottle requires a higher weighing standard magnesium sulfate: burning magnesium sulfate at 800 degrees for 1 hour, cooling and weighing, dissolving it in 100 mL (1+100) sulfuric acid solution, transferring it to 1 L measuring bottle, shaking uniformly at constant volume, and obtaining a solution containing 1 mg/mL of magnesium.
