50 ml of 1 M oxalic acid (mol. wt. = 126) is shaken with 0.5 g of wood charcoal. The final
concentration of soultion after adsorption is 0.5 M. Calculate the amount of oxalic acid adsorbed
per gram of charcoal.

Text Solution

Verified by Experts

Initial amount of oxalic acid present in `50 ml =126/1000 xx 50 = 6.3 g`
Amount of oxalic acid in 50 ml after adsprption `= 3.15 g`
Amount of oxalic acid adsorbed per gram of charcoal `3.15 xx 2`
`= 6.3 g`
