Salicylaldehyde

An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.

Dissociation

In aqueous solution, the process in which a solid ionic compound separates into its ions.

Mass Action Expression

For a reversible reaction, aA + bB cC + dD the product of the concentrations of the products (species on the right), each raised to the power that corresponds to its coefficient in the balanced chemical equation, divided by the product of the concentrations of reactants (species on the left), each raised to the power that corresponds to its coefficient in the balanced chemical equation. At equilibrium the mass action expression is equal to K, at other times it is Q.[C]c[D]d [A]a[B]b = Q, or at equilibrium K.

Nonelectrolyte
