    In an experiment, 200 mL of 0.5 M oxalic acid is shaken with 10 g of activated charcoal and filtered. The concentration of the filtrate is reduced to 0.4  M The amount of adsorption\[\left( \frac{x}{m} \right)\] is

    A) 0.9                   

    B) 1.8  

    C) 0.18                 

    D) 0.09

    Correct Answer: C

    Solution :

    [c] Mass of oxalic acid adsorbed by 10 g charcoal \[=200\times {{10}^{-3}}\left( 0.5-0.4 \right)\times 90=1.8\text{ }g\] \[\frac{x}{m}=\frac{1.8}{10}=0.18\]
