Solutions Question 4
Question 4 - 25 January - Shift 2
The number of pairs of the solution having the same value of the osmotic pressure from the following is
(Assume 100% ionization)
A. $0.500 M C_2 H_5 OH(aq)$ and $0.25 M KBr(aq)$
B. $0.100 M K_4[Fe(CN)_6]$ (aq) and $0.100 M$
$FeSO_4(NH_4)_2 SO_4(aq)$
C. $0.05 M K_4[Fe(CN)_6][aq]$ and $0.25 M NaCl$ (aq)
D. $0.15 M NaCl(aq)$ and $0.1 M BaCl_2(aq)$
E. $0.02 M KCl . MgCl_2 \cdot 6 H_2 O(aq)$ and $0.05 M$ $KCl(aq)$
Show Answer
Answer: (4)
Solution:
$\pi=iCRT$
$\pi \propto iC$
A, B, D and E have same value of osmatic pressure.
