Very dilute solutions which show deviations (positive or negative) from Raoult's law are called

Which of the following does not show positive deviation from Raoult's law ?

True or false For solution showing positive deviation form Raoult's law DeltaV_(mi x i ng)=-ve and DeltaH_(mi x i ng)=+ve

A binary solution of liquids A and B will show positive deviation from Raoult's law if it fulfils the following condition:

True or false Solution of ethanol and cyclohexane shows positive derivation from Raoult's law.

Vapour pessure of a liquid or a solution is the pressure exerted by the vapour in equilibrium with the liquid or solution at a particular temperature. It depends upon the nature of the liquid and temperature. It depends upon the nature of the liquid and temperature. According to Raoult's law in a solution, the vapour pressure of a component at a given temperature is equal to the mole fraction of that component in solution multiplied by the vapour pressure of that component in hte pue state. this solution in which each component obeys Raoult's law are called ideal solutions. there are two types of non ideal solutions, showing positive deviations and negative deviations from ideal behaviour. If liquid A and B form ideal solution, then

Missing of one positive ion and one negative ion from the crystal lattice is called

What is meant by positive and negative deviation from Raoult's law and how is the sign of delta_(mix)H related to positive and negative deviation from Raoult's law?
