The dissolution of ammonia gas in water does not obey Henry's law. On dissolving. a major portion of ammonia molecules unite with H_(2),O to form NH_(4),OH molecules. A portion of the latter again dissociates into NH_(4)^(+) , and OH^(-) ions. In solution thercfore, we have NH_(3) , molecules, NH_(4),OH molecules and NH_(4)^(+) , ions and the following equilibrium exist: NH_(3(g)) (pressure P and concentration c) rarr NH_(3(l)) + H_(2),Orarr NH_(4),OH rarr NH_(4)^(+) rarr,+OH^(-) Let c_(1) ,mol/L of NH_(3) , pass in liquid state which on dissolution in water forms c_(2) mol/ L of NH_(4),OH. The solution contains c_(3) mol/L of NH_(4)^(+) , ions. If P is the partial pressure of ammonia at equilibrium, then which of the following is constant?
