Question

what are the important contents to describe that an equation is chemical in nature? Give a suitable example.

Answer 1

⇒ A chemical reaction that involves the formation of an insoluble product (precipitate; solid) is called Precipitation reaction.

⇒The reactants are soluble, but the product formed would be insoluble and separates out as a solid.

⇒The chemical equation by which a chemical change is described is adequate for reaction in solutions, but for reactions of ionic compounds in aqueous solution (water), the typical molecular equation has different representations.

⇒A molecular equation may indicate formulas of reactants and products that are not present and eliminate completely the formulas of the ions that are the real reactants and products.
