When two liquid A and B are mixed, the solution becomes warmer. Which deviation solution exhibit from Rault's law?

10 cm^3 of a liquid A was mixed with 10 cm^3 of liquid B. The volume of the resulting solution was found to be 19.9 cm^3 . What do you conclude?

A solution of two miscible liquids (A and B) shows negative deviations, what temperature changes are expected during mixing the liquids?

Non ideal solution exhibit either positive or negative deviations from Raoult's law. What are these deviations and why are they caused? Explain with one example for each type.

Pragya tested the solubility of three different substances at different temperatures - and collected the data as given below (results are given in thefollowing table, as grams of substance dissolved in 100 grams of water to form a saturated solution). Pragya makes a saturated solution of potassium chloride in water at 353 K and leaves the solution to cool at room temperature. What would she observe as the solution cools? Explain.
