Question
When 0.1 mole of ammonia is dissolved in sufficient water to make 1 litre of solution. The solution is found to have a hydroxide ion concentration of 1.34 x 10-3 . The dissociation constant of ammonia is
Joshi sir comment
NH3 + H2O---------------------> NH4+ + OH-
0.1 0 0
0.1(approx) 1.34*10-3 1.34*10-3
now calculate dissociation constant
