Question

Which of the following aqueous solution has highest boiling point?

• A. $0.1\, M$ Glucose
• B. $0.1\, M NaCl$
• C. $0.1\, K _{2} SO _{4}$
• D. $0.1\, M K _{4}\left[ Fe ( CN )_{6}\right]$

Answer 1

Answer: (D)

$\bullet$ Higher the value of $(ixM)$, higher will be the boiling point of solution.
