Q.
Which will form maximum boiling point azeotrope
Solutions
Solution:
The solutions (liquid mixture) which boils at constant temperature and can distil as such without any change in composition are called azeotropes.
Solution of $HNO _3$ and $H _2 O$ will form maximum boiling point azeotrope. Maximum boiling azeotropes show negative deviation from Raoult's law.
Boiling point of the azeotrope of these two solutions is $393.5 \,K$
