Vedclass · Answer

(D) Two solutions are isotonic if they have the same osmotic pressure $(\pi)$ at the same temperature.$\pi = i 	imes C 	imes R 	imes T$,where $i$ is the van't Hoff factor and $C$ is the molar concentration.For option $D$:For $0.1 \ M$ $Ba(NO_3)_2$,$i = 3$ $(Ba^{2+} + 2NO_3^-)$,so $\pi_1 = 3 	imes 0.1 	imes R 	imes T = 0.3 \ RT$.For $0.1 \ M$ $Na_2SO_4$,$i = 3$ $(2Na^+ + SO_4^{2-})$,so $\pi_2 = 3 	imes 0.1 	imes R 	imes T = 0.3 \ RT$.Since $\pi_1 = \pi_2$,the solutions are isotonic.

Which of the following pairs of solutions can be isotonic at the same temperature?
