A binary liquid solution is prepared by mixing n-heptane and ethanol. Which one of the following statements is correct regarding the behaviour of the solution?
The solution formed is an ideal solution
The solution is non-ideal, showing +ve deviation from Raoult’s law.
The solution is non-ideal, showing –ve deviation from Raoult’s law.
n-heptane shows +ve deviation while ethanol shows –ve deviation from Raoult’s law.
B.
The solution is non-ideal, showing +ve deviation from Raoult’s law.
On mixing n-heptane and ethanol; strong interactions are replaced by weak interaction and hence it kes non-ideal solution with positive deviation.
