alleryThe nitric acid and water azeotrope holds nitric acid at about:
A32 per cent
B95 per cent
C50 per cent
D68 per cent
Answer & Solution
Correct answer: D. 68 per cent
1. This pair forms a maximum boiling azeotrope.
2. Its composition is fixed at one particular ratio by mass.
3. That ratio is about 68 per cent nitric acid to 32 per cent water.
