In an experiment, 500ml of 0.5M hydrated oxalic acid is shaken with 5g of activated charocal and filtered. The conc. of filtrate is 0.4 M. If the extent of adsorption (x/m) is 1.26 xx 10^(-x) then x = __?

Answer»


Solution :`0.5 = (WT)/126 cdot 1000/500 , wt = 31.5 , 0.4 = (wt)/(126) cdot (1000)/(500) = 25.2`
adsorbed `31.5 = 25.2 5 GR to 6.3 1 to ? 1.26`.
