3 g of activated charcoal was added to mL of acetic acid solution (0.06N) 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 :
Option 1)
18 mg |
Option 2)
36 mg |
Option 3)
42 mg |
Option 4)
54 mg |
As we learnt in
Concept of limiting reagent and excess reagent -
The reactant which gets consumed and thus limits the amount of product formed is called the limiting reagent.
- wherein
CH4 (g) + 2O2 (g) → CO2 (g) + 2 H2O (g) ;
In this reaction, if 1 mole of methane and 1 mole of oxygen are taken then oxygen would be limiting reagent.
