Question

a sol containing 1 23g of Ca(NO3)2 in 10 g of
water boils at 100 93*C calculate the degree of ionisation of the
nitrate (Kb=0 52)

Geetha · Accepted Answer

According to Boling point elevation∆Tb = Kb × m =  Kb × W2M2 W1 × 1000 = 0
52 × 1
23164 × 10 × 1000  = 0
39Tb-Tb0 = 0 39Tb = 0
39 + 100 = 100
