JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
When \(200 \,mL\) of \(0.2\, M\) acetic acid is shaken with \(0.6\, g\) of wood charcoal, the final concentration of acetic after adsorption is \(0.1 \,M\). The mass of acetic acid adsorbed per garm of carbon is \(......\,g.\)
- A \(1\)
- B \(0.2\)
- C \(2\)
- D \(20\)
Answer & Solution
Correct Answer
(C) \(2\)
Step-by-step Solution
Detailed explanation
weight of wood charcoal \(=0.6\, g\) Mass of acetic acid adsorbed \(=\frac{ M _{1} V _{1}- M _{2} V _{2}}{1000} \times 60\) \(=\frac{0.2 \times 200-0.1 \times 200}{1000} \times 60\) \(=1.2 \,g\) Mass of acetic acid adsorbed per gram of carbon \(=\frac{1.2}{0.6}=2\)
