Does salt change its structure and composition after a reaction?

Salt, also known as an ionic compound, undergoes chemical reactions by exchanging ions. When a salt dissolves in water, its constituent ions separate and disperse throughout the solution. These ions can then interact with other ions present in the solution, leading to the formation of new ionic compounds.

For example, when sodium chloride (NaCl) dissolves in water, the sodium (Na+)

and chloride (Cl-) ions dissociate. If silver nitrate (AgNO3) is added to this solution, a precipitation reaction occurs, resulting in the formation of silver chloride (AgCl) and sodium nitrate (NaNO3). In this reaction, the sodium and nitrate ions remain unchanged, while the silver and chloride ions combine to form a new compound.

Therefore, while the structure and composition of the individual ions remain the same throughout the reaction, the overall composition of the salt changes as new ionic compounds are formed.
