The mass x of a solute adsorbed per gram...

The mass x of a solute adsorbed per gram of a solid adsorbetn is given by the Freundlich adsorption isotherm as `a = kC^n`, where k and n are 0. 160 and 0.431 respectively. Calculate the amount of acetic acid that 1 kg of charcoal adsorbs from 0.837 M vinegar solution.

Text Solution

Verified by Experts

Mass of acetic acid adsorbed by 1 g of charcoal , ` x= kc^(n)`
`= 0.160 xx (0.837)^(0.431) = 0.148 g`
Mass of acetic acid adsorbed by 1000 g of charcoal ` = 0.148 g xx 1000 = 148 g`
