Write down the reaction equation: Mg → MgSO4 → Mg (OH) 2 → MgO → MgCL2 → MgCO3
To carry out the above chain of reactions, the following reactions must be performed:
The reaction between substances such as magnesium and sulfuric acid. As a result of the reaction, a magnesium sulfate salt is formed and hydrogen is released. The molecular equation of the reaction can be written as follows:
Mg + H2SO4 = MgSO4 + H2
The reaction between substances such as magnesium sulfate and sodium hydroxide. As a result of the reaction, magnesium hydroxide and sodium sulfate salt are formed. The molecular equation of the reaction can be written as follows:
MgSO4 + 2 NaOH = Mg (OH) 2 + Na2SO4
3. Dissociation reaction of magnesium hydroxide and magnesium oxide to magnesium oxide and water. The molecular equation of the reaction can be written as follows:
2 Mg (OH) 2 = 2 MgO + 2 H2O
The reaction between substances such as magnesium oxide and hydrochloric acid. As a result of the reaction, a magnesium chloride salt is formed and water is released. The reaction record looks like this:
MgO + 2 HCl = MgCl2 + H2O
The reaction takes place between substances such as magnesium chloride and potassium carbonate salt. As a result of the reaction, a potassium chloride salt and a magnesium carbonate salt are formed. The molecular equation of the reaction can be written as follows:
MgCl2 + K2CO3 = 2 KCl + Mg2CO3.
