Equilibrium constant expression can be applied to?

Explanation

An equilibrium constant expression can be applied to an aqueous solution of table salt. 

Explanation:

An equilibrium constant expression is used for reversible reactions where the concentrations of reactants and products reach a constant state.

Table salt (sodium chloride) dissociates into Na+ and Cl- ions in water, and this dissociation can be considered a reversible reaction. Thus, the equilibrium constant can be applied to this system.
