  • question_answer Solute A is a ternary electrolyte and solute B is a non-eletrolyte. If \[0.1\text{ }M\] solution of solute B produces an osmotic pressure of 2P, then \[0.05\text{ }M\]solution of A at the same temperature will produce an osmotic pressure equal to

    A)  \[1.5\,P\]                    

    B)  \[2\,P\]

    C)  \[3\,P\]                       

    D)  P

    Correct Answer: C

    Solution :

    \[0.05\text{ }M\] solution of \[A=3\times 0.05\,M\] ion = \[0.15\text{ }M\] ions \[0.1\text{ }M\] solution of B (non-electrolyte) has osmotic pressure \[=2P\] \[\therefore \] \[0.15\text{ }M\] solution will have osmotic pressure\[=\frac{2P}{0.1}\times 0.15=3P\]
