3 g of activated charcoal was added to 50 mL of acetic acid solution (0.06 N) in a flask. After an hour it was filtered and the strength of the filtrate was found to be 0.042 N. The amount of acetic acid adsorbed (per gram of charcoal) is

View answer and explanation

Correct option: A

18 mg

Option A (18 mg) is correct because it represents the amount of acetic acid adsorbed per gram of charcoal, calculated from the change in normality.
