A solution may be defined as a Homogeneous mixtures of a single phase containing one or more of the chemical species dispersed on a molecular scale.
SOLUTE AND SOLVENT
(a) The component whose physical state is same as that of resulting solution is called as Solvent and the other component whose physical state changes is termed as Solute. e.g. In a homogenous mixture of Na(s) and Hg(l) resulting in the formation of NaHg(s), Na(s) is considered as solvent and Hg(l) is termed as Solute which is contrary to the common belief that liquids are solvents.;
(b) When both components are having the same phase as that of that the resulting solution and the relative amount of one substance in a solution is much greater than that of the other, the substance present in greater amount is generally regarded as the solvent.
METHODS OF EXPRESSING CONCENTRATIONS OF SOLUTIONS
The concentration of solutions are generally expressed in the following ways: Solute: designated as ‘b’ Solvent: designated as ‘a’
