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

If 1.27 g of iodine is liberated,when 10 ml solution of H2O2 is reacted with acidified KI solution.Then the volume strenghth of H2O2 is.?
 
 
Meq of H2O2 = Meq of I2 (w/34)*1000 = [1.27/(254/2)]*1000 w=0.34 g Thus 0.34 g of H2O2will give =(11.2/34)*.34 =0.028 litre =28 ml Thus volume strength of H2O2is = 28/10=2.8...
