58.5 g of NaCl and 180 g of glucose were separately dissolved in 1000 mL of water. Identify the correct statement regarding the elevation of boiling point of the resulting solution.

Options

  1. ANaCl solution will show higher elevation of boiling point.
  2. BGlucose solution will show higher elevation of boiling point.
  3. CBoth the solution will show equal elevation of boiling point.
  4. DNone will show boiling point elevation.

Correct answer

A. NaCl solution will show higher elevation of boiling point.

Step-by-step solution

aligned 58.5 ~g NaCl & = 58.5 58.5 ~mol & =1 ~mol 180 ~g of glucose & = 180 180 =1 ~mol aligned Thus, we have 1 M NaCl and 1 M glucose solution. But NaCl dissociates in the solution and glucose does not dissociates. Thus particle concentration is more in NaCl . Hence, NaCl solution will have higher elevation in boiling point.
