An azeotropic solution of two liquids has boiling point lower than either of them when it
An azeotropic solution of two liquids has boiling point lower than either of them when it
shows negative deviation from Raoult’s law
shows no deviation from Raoult’s law
shows positive deviation from Raoult’s law
is saturated
Solution
In case of positive deviation from Raoult's law, the observed vapour pressure is greater than the ideal vapour pressure and boiling point of azeotrope becomes lower than either of pure liquid.
