Question

Write the dissociation reaction and the corresponding K_a equilibrium expression for each of the following acids in water. (For the dissociation reaction, include states-of-matter under the given conditions in your answer. Use the lowest possible whole number coefficients. Concentration equilibrium expressions take the general form: K_c = [HCl]² / [H₂] . [Cl₂].)
