Question

Write the observations of all physical tests for magnesium sulphate​

Answer 1

Answer:

Magnesium sulfate or magnesium sulphate (in British English) is a chemical compound, a salt with the formula MgSO

4, consisting of magnesium cations Mg2+

 (20.19% by mass) and sulfate anions SO2−

4. It is a white crystalline solid, soluble in water but not in ethanol.

Magnesium sulfate is usually encountered in the form of a hydrate MgSO

4·nH

2O, for various values of n between 1 and 11. The most common is the heptahydrate MgSO

4·7H

2O, known as Epsom salt, which is a household chemical with many traditional uses, including bath salts.[1]

The main use of magnesium sulfate is in agriculture, to correct soils deficient in magnesium (an essential plant nutrient). The monohydrate is favored for this use; by the mid 1970s, its production was 2.3 million tons per year.[2] The anhydrous form and several hydrates occur in nature as minerals, and the salt is a significant component of the water from some springs.
