Define an ideal solution and write one of its characteristics.

Explanation

The solutions which obey Raoult.s law over the entire range of concentrations are called ideal solutions. Ideal solutions have the following characteristics :
The enthalpy of mixing of the pure components to form solution is zero and the volume of mixing is also zero i.e.,
` Delta_(mix) = H= 0 " and " Delta_(mix) V = 0`
