    Those solutions that follow Raoult's law are called ideal solutions. Those solutions that don't follow Raoult's law are known as non-ideal solutions.

    Electrical cunductivity of metals decrease with increase of temperature because on heating the positive ions of the metal atom start vibrating and produce hinderance in the flow of elwctrons .The electrical conductivity of semiconductor increase with increase in temperature because more electron can jump to the conduction band.

    Yogita Ingle 7 years, 6 months ago

    Solutions can be broadly categorized into two types:
    Homogeneous solutions:  Solutions with uniform composition and properties throughout the solution are known as homogenous solution. E.g. solution of salt or sugar in water, cough syrup, cup of coffee, Mouthwash, perfume are homogeneous mixture of chemicals and dyes, etc.
    Heterogeneous solutions:  Solutions with non-uniform composition and properties throughout the solution are known as heterogeneous solution. E.g. solution of water and sand, solution of oil and water, water and chalk powder, etc.

    Yogita Ingle 7 years, 6 months ago

    The solutions which obey Raoult’s Law at every range of concentration and at all temperatures are called Ideal Solutions. We can obtain ideal solutions by mixing two ideal components that is, solute and a solvent having similar molecular size and structure. For Example, consider two liquids A and B, and mix them. The formed solution will experience several intermolecular forces of attractions inside it, which will be:

    A – A intermolecular forces of attraction

    B – B intermolecular forces of attraction

    A – B intermolecular forces of attraction

    The solution is said to be an ideal solution, only when the intermolecular forces of attraction between A – A, B – B and A – B are nearly equal.

    Metallic substances will conduct electricity in both solid and molten state because they are immersed in sea of electrons. Ionic Substances conduct electricity only in molten state because in solid state their intermolecular forces are very high and thus can oscillate only about their mean position. In molten state, they get ionised and thus become carriers of charge in the Electrolyte.
