    Give one example each for non-ideal solution showing positive deviation and non-ideal solution showing negative deviation.

    Mathematically, this from of the Raoult's can be given as: P_("total"=P_(1)^(0)X_(1)+P_(2)^(0)X_(2) . Solution which obey Raoult's law over the entire range of concentration are known as ideal solution . two types of deviation from Raoult's law, that is, positive and negative deviations are observed. Azeotrons arise due to very large deviation from Raoult's law. then which of the following are correct

    The vapour pressure of a solvent is lowered by the presence of the non-volatile solute in the solution and this lowering of vapour pressure of the solvent is governed by Raoult's law , according to which the relative lowering of vapour pressure of the solvent over a solution is equal to the mole fraction of a non-volatile solute present in the solution. Howerver, in a case of binary liquid solution, if both the components of the solution are volatile then another from of Raoult's law is used . Mathematically, this from of the Raoult's can be given as: P_("total"=P_(1)^(0)X_(1)+P_(2)^(0)X_(2) . Solution which obey Raoult's law over the entire range of concentration are known as ideal solution . two types of deviation from Raoult's law, that is, positive and negative deviations are observed.
