After studying this Unit, you will be
able to
·
describe the formation of different
types of solutions;
·
express concentration of solution
in different units;
·
state and explain Henry’s law and
Raoult’s law;
·
distinguish between ideal and
non-ideal solutions;
·
explain deviations of real solutions
from Raoult’s law;
·
describe colligative properties of
solutions and correlate these with
molar masses of the solutes;
·
explain abnormal colligative
properties exhibited by some
solutes in solutions In normal life we rarely come across pure substances Most of these are mixtures containing two or more pure
substances Their utility or importance in life depends
on their composition
