The mixture that forms maximum boiling azeotrope is

The mixture that forms maximum boiling azeotrope is

Options

  1. AWater and Nitric Acid
  2. BEthanol and Water
  3. CAcetone and Carbon disulphide
  4. DHeptane and Octane

Correct answer

A. Water and Nitric Acid

Step-by-step solution

The solutions that show large negative deviation from Raoult’s law form maximum boiling azeotrope at a specific composition. Nitric acid and water is an example of this class of azeotrope. This azeotrope has the approximate composition, 6868 % nitric acid and 3232 % water by mass, with a boiling point of 393.5K.393 . 5K .
