The dissolution of ammonia gas in water does not obey Henry. s law. On dissolving , a major portion of ammonia molecules unite with H_2O to form NH_4 OH molecules . A portion of the latter again dissociates into NH_4^(+) and OH ^(-) ions. In solution therefore , we have NH_3 molecules, NH_4OH molecules and NH_4^(+) ions and the following equilibrium exist : NH_(3(g) ) (pressure P and concentration c) hArr NH_(3(i)) +H_2O hArr NH_4 OH hArr NH_4^(+) +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. The dissociation constant of NH_4 OH can be given as :
