The equilibrium constant expressionThe ratio of the concentrations of products in a balanced chemical equation, each concentration raised to the power of its coefficient, divided by the concentrations of reactants, each raised to the power of its coefficient; at equilibrium this ratio has the value of the equilibrium constant. for the dissolution of an electrolyteA substance that dissolves to produce a solution containing ions, which cause the solution to conduct electricity.; the reactantA substance consumed by a chemical reaction. is a solidA state of matter having a specific shape and volume and in which the particles do not readily change their relative positions. and its concentrationA measure of the ratio of the quantity of a substance to the quantity of solvent, solution, or ore. Also, the process of making something more concentrated. does not appear in the expression, which is a productA substance produced by a chemical reaction. of the concentrations of the products (raised the to appropriate powers).
