Which of the following graph is obtained for mixture of these two binary volatile liquids :
HNO3 (68%)+H2O(32%)
Open in App
Solution
The correct option is A
HNO3 (68%)+H2O(32%) form a maximum boiling azeotrope at these concentrations.
The given mixture boils at 393.5 K which is higher than each of the component's boiling point.
Maximum boiling mixtures are formed by non-ideal solutions showing negative deviation.
Vapour pressure is minimum at azeotropic concentration
So, (a) is correct.
