Question

Two solutions $S_1$ and $S_2$ containing 0.1 M NaCl (aq) and 0.05 M $BaC{l}_2\left(aq\right)$ are separated by semipermeable membrane. Which among the following statement(s) is/are correct? (Assume complete dissociation of both the electrolytes).

• A. $S_1$ and $S_2$ are isotonic
• B. $S_1$ is hypertonic while $S_2$ is hypotonic
• C. $S_1$ is hypertonic while $S_2$ is hypertonic
• D. Osmosis will take place from $S_1$ to $S_2$

Answer 1

The correct option is B

$S_1$ is hypertonic while $S_2$ is hypotonic

$S_1$ is hypertonic while $S_2$ is hypotonic and osmosis occurs from $S_2$ to $S_1.$
