Which of the following solutions are isotonic with respect to 0.5 M NaCl solution having degree of dissociation $= 0.8$ .

Answer:

A, B, C, D

Solution:

For NaCl :-

ic $= 0.5 \times [1 + (2 - 1) 0.8] = 0.9 M$

For Sucrose solution :-

ic $= \frac{153.9}{342} \times 2 = 0.9 M$

For $Na_{2} SO_{4}$ solution :-

ic $= 0.3 \times 3 = 0.9 M$

For NaOH :- ic $= \frac{1.8}{40} \times 10 \times 2 = 0.9 M$

For Benzoic acid :- ic $= 1.2 \times \frac{3}{4} = 0.9$
