Which of the following pair of solutions is isotonic?
1 \(0.001 \mathrm{M} \mathrm{Al}_2\left(\mathrm{SO}_4\right)_3\) and \(0.01 \mathrm{M} \mathrm{BaCl}_2\)
2 \(0.001 \mathrm{M} \mathrm{CaCl}_2\) and \(0.001 \mathrm{M} \mathrm{Al}_2\left(\mathrm{SO}_4\right)_3\)
3 \(0.01 \mathrm{M} \mathrm{BaCl}_2\) and \(0.001 \mathrm{M} \mathrm{CaCl}_2\)
4 \(0.01 \mathrm{M} \mathrm{BaCl}_2\) and 0.015 M NaCl
Explanation:
(d) Isotonic solutions are those which have same osmotic pressure at a given temperature.
For \(0.01 \mathrm{M} \mathrm{BaCl}_2, i=3\)
\(\pi=i C R T=3 \times 0.01 R T=0.03 R T\)
For \(0.015 \mathrm{M} \mathrm{NaCl}, i=2\)
\(\therefore \pi=2 \times 0.015 R T=0.03 R T\)
Therefore, \(0.01 \mathrm{M} \mathrm{BaCl}_2\) and 0.015 M NaCl are isotonic.
