Question

For an ideal solution containing a non-volatile solute, which of the following expression is correctly represented?
Where $m$ is the molality of the solution and $K_{b}$ is molal elevation constant

• A. $\Delta\,T_{b}=K_{b}\times m$
• B. $\Delta\,T_{b}= K_{b} \times M$
• C. $\Delta\,T_{b}=K_{b} \times 2m$
• D. $\Delta\,T_{b}=K_{b}\times 2M$

Answer 1

Answer: (A)

$\Delta \, T_{b} =i\times K_{b}\times m$
$i=1$, for an ideal solution
