Question

What is Electrophoresis?

0.3 g of acetic acid (M = 60 g mol⁻¹) dissolved in 30 g of benzene shows a depression in freezing point equal to 0.45°C. Calculate the percentage association of acid if it forms a dimer in the solution. (Given: Kf for benzene = 5.12 K kg mol⁻¹)

Why is boiling point of 1M NaCl solution more than that of 1M glucose solution ?

A non-volatile solute 'X' (molar mass = 50 g mol⁻¹) when dissolved in 78g of benzene reduced its vapour pressure to 90%. Calculate the mass of X dissolved in the solution.
