Question

Which statement is correct for solutions show positive deviation? *​

Answer 1

A mixture of ethanol and water shows positive deviation from Raoult's law. The intermolecular forces present are weaker than those present in the ideal solution. The total vapour pressure of the solution is greater than the total vapour pressure of an ideal solution.

Answer 2

Answer:

Positive deviations is usually shown by solutions having alcohol. Positive deviation happens due to the breaking of hydrogen bonds which requires energy. Negative deviation is usually shown by solutions having acids. negative deviations happens due to formation of hydrogen bonds in the solution which releases energy.
