Q. $100 \,mL$ of $0.6 \,M$ acetic acid is shaken with $2 \,g$ activated carbon. The final concentration of the solution after adsorption is $0.5\, M$. What is the amount of acetic acid adsorbed per gram of carbon?

Surface Chemistry

Solution:

Mass of acetic acid adsorbed by $2 \,g$ charcoal
$= 100 \times 10^{-3} \times (0.6 - 0.5) \times 60 $
$\Rightarrow 0.6$
$\frac{x}{m} = \frac{0.6}{2}$
$\Rightarrow 0.3$
