Relative lowering of a solvent in binary solution is 0.85. What is the mole fraction of the solute?
Answers
Answer:
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. For example, the properties of
brass (mixture of copper and zinc) are quite different
from those of German silver (mixture of copper, zinc
and nickel) or bronze (mixture of copper and tin);
1 part per million (ppm) of fluoride ions in water
prevents tooth decay, while 1.5 ppm causes the tooth
to become mottled and high concentrations of fluoride
ions can be poisonous (for example, sodium fluoride is
used in rat poison); intravenous injections are always
dissolved in water containing salts at particular ionic
concentrations that match with blood plasma
concentrations and so on.
In this Unit, we will consider mostly liquid
solutions and their formation. This will be followed by
studying the properties of the solutions, like vapour
pressure and colligative properties. We will begin with
types of solutions and then various alternatives in
which concentrations of a solute can be expressed in
liquid solution.
