What is Mg2SO7? Important knowledge about Mg2SO7.

Firstly, please note that the molecular form Mg₂SO₇ does not exist in actual chemistry because it violates the electron arrangement rule. However, we can assume it exists for teaching purposes.

1. Definition of Mg₂SO₇

1.1. Names
1.1.1 Common name: Magnesium sulfate heptahydrate
1.1.2 English name: Magnesium sulfate heptahydrate
1.2. Atomic mass: total is 120.4 g/mol (24.3 g/mol for Magnesium and 96.1 g/mol for Sulfate)
1.3. Atomic mass and molecular structure: Molecule consists of 2 Mg₂+ ions and 1 SO₄^2- ion
1.4. Ion structure: Mg₂+ is an ion carrying a positive charge and SO₄^2- is an ion carrying a negative charge

2. Properties of Mg₂SO₇

2.1 Physical properties of Mg₂SO₇: In solid form, colorless, odorless and has a neutral pH if we assume it exists.
2.2 Chemical properties of Mg₂SO₇: Can’t be determined because it doesn’t exist in reality.

3. Common chemical equations with MgSO₄, a substitute for Mg₂SO₇, including reactions with metals, acids, non-metals and salts, can be found in chemistry textbooks.

4. Preparation of Mg₂SO₇

Since Mg₂SO₇ does not exist in reality, there is no way to prepare it in the laboratory or the industry. Instead, we may prepare MgSO₄, the substitute, through a chemical reaction between magnesium and sulfuric acid.
