The solution which shows negative or positive deviation from Raoult's law is called:

For an ideal solution,the correct option is

When ethanol is mixed with acetone,what happens to the heat?

At $T(K)$,the vapour pressures of two liquids,heptane and octane are $106 \ kPa$ and $47 \ kPa$ respectively. If $25 \ g$ of heptane and $57 \ g$ of octane form an ideal solution,at $T(K)$ the vapour pressure of solution in $kPa$ is :

Which pair of liquids shows positive deviation from Raoult's law?

$A$ mixture of phenol and aniline shows negative deviation from Raoult's law. This is due to the formation of
