$B$ 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.

Assertion : If one component of a solution obeys Raoult's law over a certain range of composition,the other component will not obey Henry's law in that range.
Reason : Raoult's law is a special case of Henry's law.
