Vedclass · Answer

(B) The boiling point elevation is a colligative property,which depends on the number of particles (van't Hoff factor,$i$) in the solution. For $1\%$ solutions,the molarity is approximately the same. Glucose $(C_6H_{12}O_6)$ and urea $(NH_2CONH_2)$ are non-electrolytes,so $i = 1$. $NaCl$ dissociates as $NaCl \rightarrow Na^+ + Cl^-$ $(i = 2)$. $ZnSO_4$ dissociates as $ZnSO_4 \rightarrow Zn^{2+} + SO_4^{2-}$ $(i = 2)$. Since the molar mass of $NaCl$ $(58.44 \ g/mol)$ is lower than that of $ZnSO_4$ $(161.47 \ g/mol)$,a $1\%$ solution of $NaCl$ contains more moles of solute per unit volume than a $1\%$ solution of $ZnSO_4$. Therefore,the $1\%$ solution of $NaCl$ has the highest number of particles and the highest boiling point.
