MCQ

If $'A'$ contains $2\%\,NaCl$ and it separated by a semipermeable membrane from $'B'$ which contains $10\%\,NaCl,$ which event will occur ?

A
$NaCl$ will flow from $'A'$ to $'B'$
B
$NaCl$ will flow from $'B'$ to $'A'$
✓
Water will flow from $'A'$ to $'B'$
D
Water will flow from $'B'$ to $'A'$

✓

Answer

Correct option: C.

Water will flow from $'A'$ to $'B'$

c
${\alpha=\frac{i-1}{n-1}} $

$0.9=\frac{i-1}{2-1} $ $\therefore \quad i=1.9 $

${\pi =i C R T=1.9 \times 0.002 \times 0.082 \times 300}$
