$B$ and $D$ only

Vedclass · Answer

(D) Incorrect. $\Delta T_b = i 	imes K_b 	imes m$. For $NaCl$,$i=2$,and for urea,$i=1$. Thus,elevation is not the same.$(B)$ Correct. Azeotropic mixtures boil at a constant temperature and have the same composition in both liquid and vapour phases.$(C)$ Incorrect. Osmosis always takes place from a hypotonic solution (lower concentration) to a hypertonic solution (higher concentration) through a semi-permeable membrane.$(D)$ Correct. Molarity $M = \frac{\% 	imes 10 	imes d}{M_{solute}} = \frac{32 	imes 10 	imes 1.26}{98} \approx 4.11 \ M$,which is approximately $4.09 \ M$.$(E)$ Incorrect. When $KI$ is added to $AgNO_3$ (excess $AgNO_3$),$AgI$ adsorbs $Ag^+$ ions to form a positively charged sol $(AgI/Ag^+)$.Therefore,only statements $(B)$ and $(D)$ are correct.

The elevation in the boiling point of an aqueous urea solution is $0.104 \ K$. What is its $\Delta T_{f}$ (in $K$) value? (Given for water: $K_{b} = 0.52 \ K \ kg \ mol^{-1}$,$K_{f} = 1.86 \ K \ kg \ mol^{-1}$)

An aqueous solution of $NaCl$ shows the depression of freezing point of water equal to $0.372 \, K$. The boiling point of $BaCl_2$ solution of same molality will be .........$^oC$. $[K_f(H_2O) = 1.86 \, K \, kg \, mol^{-1}; K_b(H_2O) = 0.52 \, K \, kg \, mol^{-1}]$

At $300 \ K$,an ideal solution is formed by mixing $460 \ g$ of toluene with $390 \ g$ of benzene. If the vapour pressure of pure toluene and pure benzene at $300 \ K$ are $32 \ mm$ and $40 \ mm$ respectively,the mole fraction of toluene in the vapour phase is:

What is boiling point? What is freezing point?

$1 \, \text{mole}$ of liquid $A$ and $2 \, \text{moles}$ of liquid $B$ make a solution having an observed vapour pressure of $42 \, \text{torr}$. The vapour pressures of pure $A$ and pure $B$ are $45 \, \text{torr}$ and $36 \, \text{torr}$ respectively. The described solution:
