Question

The mixture that forms maximum boiling
azeotrope is:
(1) Water + Nitric acid
(2) Ethanol + Water
(3) Acetone + Carbon disulphide
(4) Heptane + Octane

Answer 1

Correct option  (1) Water + Nitric acid

Explanation:

Solutions showing negative deviation from Raoult's law form maximum boiling azeotrope Water and Nitric acid → forms maximum boiling azeotrope

Answer 2

Hey !

Note :- Maximum boiling azeotropes it refers to ''Negative deviation''

Negative deviation (Vapour pressure) (Amount of vapours)

The maximum boiling azeotrope is shows by negative deviation solution so therefore it refers to H₂O and HNO₃ mixture.
