Question
what will be the value of molar conductance for 0.001M aqueoussolution for NH3 ? giveen k =1.6*10-5 and equivalent conductance=0.0238
Joshi sir comment
NH3 + H+(aq) = NH4+
0.001 0 at start
0.001(1-α) 0.001α at eq.
now k = 0.001α / 0.001(1-α)
solve this equation for α and getconcentration of NH4+
then use the formula molar conductance = eq. conductance / concentration of NH4+
