A) \[0.5{}^\circ C\]
B) \[0.2{}^\circ C\]
C) \[0.06{}^\circ C\]
D) \[0.03{}^\circ C\]
Correct Answer: B
Solution :
Elevation in boiling point is a colligative property as it depends upon the number of particles. \[\Delta {{T}_{b}}\propto n\] For sucrose, \[n=1,\Delta {{\Tau }_{b}}=0.1{{\,}^{o}}C.\] For\[NaCl,\,n=2,\,\Delta {{\Tau }_{b}}=0.2{{\,}^{o}}C.\] Hence, the correct option is [b].You need to login to perform this action.
