Question

a) Wtrite the equation for dissociation of ammonium hydroxide (ammonia), its equilibrium expression, and the value of it's Kb:

b)Write the net ionic equation for the reaction of water with ammonium chloride, the equilibrium expression, and the value of it's Keq:

c)Multiply together the two equilibrium expressions you derived in parts (a) and (b):

d) Multiply the two values of the equilibrium constants you derived in parts (a) and (b):

e) What will always be true of Ka x Kb for any conjugate acid/base pair?

Explanation / Answer

b

Ammonium chloride, NH4Cl, is soluble in water.

NH4Cl(s) --H2O-> NH4+ + Cl- ...... Kc is very large

Ammonium chloride may very well be the result of strong intermolecular bonding between ammonia, NH3 and hydrogen chloride gas, HCl. ..... NH3
