What is the mechanism by which solute is dissolved in non polar solvents? Explain briefly. (5 mark)

Expert Solution

Ans: Any solute dissolves in a solvent on the following factors-

> Favourable interaction

>Free energy change of solute and solvent

The mechanism of solute-solvent interaction involves 3 steps:-

1) Dettachment of solute from bulk form

( solute bulk) (solute bulk-1) + (dettached solute)

2) Formation of vaccant side in solvent

(solvent) (solvent with vaccant site) + ( free solvent molecule)

3) Insertion of dettached solute molecule in vaccant site of solvent

+ (solvent with embeded solute molecule)

As in case of non-polar solvent, it don't have dielectric constant , not have ability to form covalent bond and neither it can form H-bond. Hence non-polar solvents only are able to dissolve non-polar solutes by inducing dipole moment.

16.636 g of a non-volatile solute is dissolved in 410.0 g of water. The solute does not react with water nor dissociate in solution. Assume that the resulting solution displays ideal Raoult's law behaviour. At 90°C the vapour pressure of the solution is 517.01 torr. The vapour pressure of pure water at 90°C is 525.80 torr. The molar mass of the solute is 43.0 g/mol. Now suppose, instead, that 16.636 g of a volatile solute is dissolved in 410.0 g of...

9.537 g of a non-volatile solute is dissolved in 220.0 g of water. The solute does not react with water nor dissociate in solution. Assume that the resulting solution displays ideal Raoult's law behaviour. At 25°C the vapour pressure of the solution is 23.498 torr. The vapour pressure of pure water at 25°C is 23.756 torr. Calculate the molar mass of the solute (g/mol). 71.1 g/mol Now suppose, instead, that 9.537 g of a volatile solute is dissolved in 220.0...

Why do non-polar solvents in thin layer chromatography cause lower Rf values? In this case, hexane was used as a solvent and benzhydrol and benzophenone were added to the TCL plate. The solvent (hexane) traveled far because I'm assuming due to capillary action, but the solutes did not travel far at all. Why?

A liquid mixture contains 60 wt% ethanol, 5 wt% of a dissolved solute, and the balance water. A stream of this mixture is fed to a distillation column operating at steady state. The streams emerging from the column have equal mass flow rates. The top stream contains 90 wt% ethanol with no solute. Solve for all the mass fractions of the bottom stream and solve for the 3 mass flow rates
