Concept explainers
Interpretation:
The reaction that results in the formation of a solid should be identified.
Concept Introduction:
A balanced chemical equation is an equation that contains same number of atoms as well as of each element of reactants and products of reaction.
For example, the reaction between lead sulphide and oxygen is as follows:
In the given reaction, the number of all atoms, on the both side are equal hence this is a balance reaction.
The most common driving forces which create product in
- Formation of a solid.
- Formation of water.
- Transfer of electrons.
- Formation of gas.
If a substance is not soluble in water than it forms precipitate. The phase of the precipitate is solid. The precipitates are formed depending on the solubility of salt in water.
