Which of the following pair of solutions can we expect to be isotonic at the same temperature?
- A 0.1 M NaCl and \(0.1 \mathrm{M} \mathrm{Na}_2 \mathrm{SO}_4\)
- B \(0.1 \mathrm{M} \mathrm{Na}_2 \mathrm{SO}_4\) and \(0.1 \mathrm{M} \mathrm{Ca}\left(\mathrm{NO}_3\right)_2\)
- C 0.1 M urea and 0.1 M NaCl
- D 0.1 M urea and \(0.2 \mathrm{M} \mathrm{MgCl}_2\)
Answer & Solution
Correct Answer
(B) \(0.1 \mathrm{M} \mathrm{Na}_2 \mathrm{SO}_4\) and \(0.1 \mathrm{M} \mathrm{Ca}\left(\mathrm{NO}_3\right)_2\)
Step-by-step Solution
Detailed explanation
\(\pi=i C R T\) When, \(i, C, T\) are same for 2 or more solution then their osmotic pressure are also same that are known as isotonic.…
