Sodium carbonate monohydrate, the chemical formula is Na2CO3 H2O, which means that each sodium carbonate molecule is combined with one water molecule.
The chemical formula of sodium carbonate decahydrate is Na2CO3 10H2O, which means that each sodium carbonate molecule is combined with ten water molecules.
The main difference between these two hydrates lies in the amount of water. These compounds are different in chemical and physical properties due to the presence of water in hydrate. For example, sodium carbonate decahydrate is solid at room temperature, and sodium carbonate monohydrate is crystal at room temperature; Sodium carbonate decahydrate will dehydrate to generate anhydrous sodium carbonate when heated, while sodium carbonate monohydrate will lose its crystal water and become anhydrous sodium carbonate.
In the field of education, this knowledge may be mentioned in chemical experiments to help students understand chemical formulas and different forms of compounds. At the same time, this knowledge may be related to the teaching content related to chemical equations, state of matter and material transformation.
