Which of the following pairs of solutions is expected to be isotonic at same temperature?
Options
- A(0.1 M ) urea and (0.1 M NaCl )
- B(0.1 M ) glucose and (0.2 M NaCl )
- C(0.1 M NaCl ) and (0.1 M CH ₃ COOH )
- D(0.1 M NaCl ) and (0.1 M KNO ₃ )
Correct answer
D. (0.1 M NaCl ) and (0.1 M KNO ₃ )
Step-by-step solution
Two solutions of same osmotic pressure (( ) ) are isotonic solutions. ( aligned ₁(0.1 M NaCl ) & =0.1 R T 2 ₂ (0.1 M KNO ₃ ) & =0.1 R T 2 aligned ) So, ( ,(0.1 M NaCl )= ₂ (0.1 M KNO ₃ ) ) at same temperature.
