Important Points to Remember on Solutions

1. Solution:

A homogeneous mixture of two or more non-reacting substances is known as solution, Homogeneity or heterogeneity depends upon particle size and states of matter present in the solution. Every solution is made up of a solvent (present in larger quantity) and one or more solute (present in smaller quantity).

2. Units of Concentration:

(i) Molarity M :

It is the number of moles of solute present per litre of solution.

M=nV=WMwVin litre=WMw1000Vin cc

M×Vin cc=WMw1000 ⇒M×VmL= millimoles

Molarity changes with temperature of the solution. Increase in temperature generally decreases the molarity. It is the most convenient method to express concentration of the solution. On dilution, molarity decreases.

(ii) Molality m : Number of moles n

of solute present per

kg of solvent.

m=nWin kg=WMWin kg=WMWin gsolvent 1000

It is independent of temperature since no volume factor is involved in the equation.

(iii) Mole fraction X :

It is the ratio of number of moles of one component to the total number of moles present in the solution.

For a system having two components

A and B ,

XA=nAnA+nB,  XB=nBnA+nB

XA+XB=1

Mole fraction is also independent of temperature.

(iv) In terms of % % by weight

= Wt. of solute  Wt. of solution ×100

% weight by volume

= Wt.of solute  Vol. of solution ×100

(In case of solid dissolved in a liquid)

% by volume

= Volume of solute  Volume of solution ×100

(In case of liquid dissolved in another liquid)

PPM= No. of parts of solute  No. of parts of solution ×106

%

by weight is independent of temperature while

%

by volume are temperature dependent.

3. Henry’ s Law:

Solubility of a gas at a given temperature in a solvent is directly proportional to its partial pressure, if

P

is the partial pressure of a gas and

Xg

is its mole fraction in solution. Then

P=KHXg , where KH

is Henry's law constant for that gas.

4. Vapour Pressure and Raoult’s law:

The pressure exerted by the vapour at the free surface of liquid (provided system is closed) is known as its vapour pressure. The

V.P.

of a pure liquid is always greater than its solution (in case of non-volatile solute).

(i) Raoult’s Law for a solution having non-volatile solute.

Xsolute =P∘-PsP∘ Xsolute →

Mole fraction of solute in solution

P∘→ V.P. of pure solvent Ps→ V.P. of solution

i.e., relative lowering of vapour pressure is equal to the mole fraction of solute.

(ii) Raoult's Law of miscible liquid-liquid solution

For ideal solution, the partial vapour pressure is directly proportional to their mole fraction at constant temperature. For two components

A and B in liquid solution. ⇒PA=PA∘XA ⇒PB=PB∘XB The total pressure

PTotal=PA+PB=PA∘XA+PB∘XB

Most of the solutions show appreciable deviations from ideal behavior known as real or non-ideal solution. In some cases, the deviation is

+ve

while in some cases deviation is

-ve .

5. Ideal and non-ideal Solutions:

The solutions which obey Raoult's law are ideal solutions and those which do not obey Raoult's law form non-ideal solution.

Ideal Solution Non-Ideal Solution

Positive Deviation Negative Deviation
