Water [Dissociation of aq . Soln ]
`NH_(3)+H_(2)O to_____`
`[NH_(4)OHhArrNH_(4)^(+)+_____` ]

Sulphuric acid [conc.] NH_(3)+H_(2)SO_(4) to_____

Burning of ammonia in oxygen NH_(3)+O_(2) to_____+______

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. Total concentration of undissociated ammonium hydroxide is

One "mole" of NH_(4)HS(s) was allowed to decompose in a 1-L container at 200^(@)C . It decomposes reversibly to NH_(3)(g) and H_(2)S(g). NH_(3)(g) further undergoes decomposition to form N_(2)(g) and H_(2)(g) . Finally, when equilibrium was set up, the ratio between the number of moles of NH_(3)(g) and H_(2)(g) was found to be 3 . NH_(4)HS(s) hArr NH_(3)(g)+H_(2)S(g), K_(c)=8.91xx10^(-2) M^(2) 2NH_(3)(g) hArr N_(2)(g)+3H_(2)(g), K_(c)=3xx10^(-4) M^(2) Answer the following: To attain equilibrium, how much % by weight of folid NH_(4)HS got dissociated?
