$0.15 \ M \ NaCl$ and $0.1 \ M \ Na_2SO_4$

Vedclass · Answer

(A) Two solutions are isotonic if they have the same molar concentration of particles (osmotic pressure).For $0.15 \ M \ NaCl$: $NaCl$ dissociates into $2$ ions ($Na^+$ and $Cl^-$). The concentration of particles $= 0.15 	imes 2 = 0.30 \ M$.For $0.1 \ M \ Na_2SO_4$: $Na_2SO_4$ dissociates into $3$ ions ($2Na^+$ and $SO_4^{2-}$). The concentration of particles $= 0.1 	imes 3 = 0.30 \ M$.Since both solutions have the same concentration of particles $(0.30 \ M)$, they are isotonic.

Which one of the following is an isotonic pair of solutions?
