Preparation of Magnesium sulphate: this chemical can be prepared by the recrystallization of industrial magnesium sulfate.
Uses of Magnesium sulphate: this chemical is used to correct magnesium deficiency in soil in agriculture and gardening. It can also be used in organic synthesis as a desiccant due to its affinity for water. Additionally, it is used in bath salts. And it is also absorbed into the skin, reducing inflammation. It is commonly used as a saline laxative. Furthermore, it can be used to treat eclampsia in pregnant women. It can be used as the electrolyte to prepare copper sulfate:
Cu + MgSO4 + 2 H2O → H2 + CuSO4 + Mg(OH)2
When you are using this chemical, please be cautious about it as the following: it is irritating to eyes, respiratory system and skin. Please do not breathe dust. And in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Moreover, you should wear suitable protective clothing to avoid contact with skin and eyes.
People can use the following data to convert to the molecule structure.
(1)Canonical SMILES: [O-]S(=O)(=O)[O-].[Mg+2]
