There is an equilibrium constant for HCl, but it is very large and the equilibrium is so far to the right that we describe it as completely dissociated. When HCl dissolves in water it produces equal numbers of H+ and Cl- ions. We describe the solution as 0.10 M HCl, but in reality we understand that it is really 0.10 M H+ and 0.10 M Cl-.
