Calculate the elevation in boiling point, for a solution of 13 .44 g of C u C l 2 in 1 k g of water using the following information (Molecular weight of CuCl 2 = 134 .4 and K b = 0 .52 Kmolal 1 )

Question

Calculate the elevation in boiling point, for a solution of 13 .44 g of C u C l 2 in 1 k g of water using the following information (Molecular weight of CuCl 2 = 134 .4 and K b = 0 .52 Kmolal 1 ), 0.05, 0.16, 0.1, 0.2

Δ T b = i . K b . m C u C l 2 → C u 2 + + 2 C l 1 0 0 ( 1 - α ) α 2 α i = 1 + 2 α Assuming 100% ionization, α = 1 So, i = 3 Δ T b = 3 × 0.52 × 0.1 = 0.156 ≅ 0.16
