Question

At same temperature, which pair of the following solutions are isotonic solutions ? (A) 0.2 M BaCl2 and 0.2 urea (B) 0.1 M urea and 0.1 M NaCl (C) 0.1 M NaCl and 0.1 M K2S04 (D) 0.1 M Ba(N03)2 and 0.1 M Na2SO4

Two solutions are isotonic if they have same molar concentrations of particles in solution. 0.1 M Ba(NO3)2 = 0.3 M ion concentration 0.1 M Na2SO4 = 0.3 M ion concentration

Q. At same temperature, which pair of the following solutions are isotonic solutions ?

0.2 M $B a C l_{2}$ and 0.2 urea

0.1 M urea and 0.1 M NaCl

0.1 M NaCl and 0.1 M $K_{2} S 0_{4}$

0.1 M $B a (N 0_{3})_{2}$ and $0.1 MN a_{2} S O_{4}$

Two solutions are isotonic if they have same molar concentrations of particles in solution.
0.1 M $B a (N O_{3})_{2}$ = 0.3 M ion concentration
0.1 M $N a_{2} S O_{4}$ = 0.3 M ion concentration
