50 ml of 1 M oxalic acid is shaken with 0.5 g of wood characoal : The final concentration of the solution after adsorption is 0.5 M. Amount of hydrated oxalic acid adsorbed per gram of charcoal is

A

3.45 g

B

3.15 g

C

6.30 g

D

6.45 g

Text Solution

Verified by Experts

The correct Answer is:
C
`w= (126xx1xx50)/(1000)=6.3 g`
Thus 1 M oxalic acid has 63 g after adosorption 0.5 M oxalic acid solution has `(6.3 g)/(2)=3.65` g
So 1 g of wood characoal adsorbs =`(3.65 xx1)/(0.5)=6.3 g`
