\(58.4 \mathrm{g}\) of \(\mathrm{NaCl}\) and \(180 \mathrm{g}\) of glucose were separately dissolved in \(1000 \mathrm{mL}\) of water. Identify the correct statement regarding the elevation of boiling point (b.p) of the resulting solutions.
- A NaCl solution will show higher elevation of boiling point
- B Glucose solution will show higher elevation of boiling point
- C Both the solutions will show equal elevation of boiling point
- D The boiling point elevation will be shown by neither of the solutions
Answer & Solution
Correct Answer
(A) NaCl solution will show higher elevation of boiling point
Step-by-step Solution
Detailed explanation
Elevation in boiling point, \(\Delta T_{b}=i \times K_{b} \times m\) Molality of NaCl solution \(=\frac{n}{W} \times 1000\) \(=\frac{58.5}{W_{\mathrm{H}_{2} \mathrm{O}}} \times 1000=\frac{1000}{\mathrm{W}_{\mathrm{M}_{2}} \mathrm{O}}\) Molality of…
