Question
Explain the following:
  1. Solution of chloroform and acetone is an example of maximum boiling azeotrope.
  2. A doctor advised a person suffering from high blood pressure to take less quantity of common salt.
✓

Answer

  1. This solution has lesser vapour pressure due to stronger interactions (hydrogen bonds) between chloroform and acetone molecules.
  2. Because higher quantity of NaCl will increase number of sodium and chloride ions in the body fluid which can increase the osmotic pressure of body fluid, i.e., blood pressure of a person.
