Solutions Question 91
Question: If for a sucrose solution elevation in boiling point is 0.1°C then what will be the boiling point of NaCl solution for same molal concentration [BHU 1998, 2005]
Options:
A) $ 0.1{}^\circ C $
B) $ 0.2{}^\circ C $
C) $ 0.08{}^\circ C $
D) $ 0.01{}^\circ C $
Show Answer
Answer:
Correct Answer: B
Solution:
Elevation in a boiling point is a colligative property as it depends upon the number of particles. -Tb µ n For sucrose, n = 1, -Tb = 0.1°C For NaCl, n = 2, -Tb = 0.2°C
