Q1 FREE PREVIEW

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.

a

NaCl solution will show higher elevation of boiling point.

b

Glucose solution will show higher elevation of boiling point.

c

Both solutions will show equal elevation of boiling point.

d

None will show boiling point elevation.

✓ Correct answer: a)

NaCl solution will show higher elevation of boiling point.

Explanation

Boiling point elevation depends on molality × van’t Hoff factor (i). NaCl (i = 2) dissociates, while glucose (i = 1) does not. Thus, NaCl solution shows higher elevation.
