Question

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

• A. $0.6$
• B. $0.3$
• C. $1.2$
• D. $1.8$

Answer 1

Answer: (B)

$0.3$

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