Question

Q. 0.067 molar aqueous solution of a binary electrolyte A+B- show 2.46 atm osmotic pressure at 27°c. what percentage of A+B- is ionised.​

Answer 1

Answer:

For AB;C=0.067M

π=2.46 atm;

T=300K

i=$\frac{\pi }{C*S*T}$

$i=\frac{2.46}{0.067*0.0821*300} =1.5$

For electrolyte AB

i=1+α

α=0.5 or 50%
