Dear laly,


Make the pulp of guava and boil it with dil. H2SO4.Then titrate it with standard KMnO4(in burette) solution till u get light pink colour.Repeat this with 1,2 and 3 days old guava fruit.
let weight of guava extract taken each time=50 g
Volume of guava extract each time in titration =10.0 ml
Normality of KMnO4 solution=1/20.
then
N1V1 = N2V2
(guava extract) (KMnO4 sol)
N1 * 10=1/20 *x
Normality of oxalate, N1=x/200
