Vedclass · Answer

(D) Two solutions having the same osmotic pressure $(\pi)$ at the same temperature are called isotonic solutions.Osmotic pressure is given by $\pi = i 	imes C 	imes R 	imes T$,where $i$ is the van't Hoff factor.For $0.1 \ M$ $NaCl$,$i = 2$ (as it dissociates into $Na^+$ and $Cl^-$),so $\pi = 2 	imes 0.1 	imes R 	imes T = 0.2 \ RT$.For $0.1 \ M$ $KNO_3$,$i = 2$ (as it dissociates into $K^+$ and $NO_3^-$),so $\pi = 2 	imes 0.1 	imes R 	imes T = 0.2 \ RT$.Since both solutions have the same osmotic pressure,they are isotonic.

Which of the following pairs of solutions is expected to be isotonic at the same temperature?
