Hydrozoan Per Oxide (H2O2) Test
Make necessary solutions:
v Potassium per manganite solution :
Process :
1.58 gm Potassium permanganate (KMnO4) + 0.5 Litter Water (H2O) for make 0.1 Normal solution
In 0.5 Litter volume metric flax. ( 3.16 KMnO4 for 1 Litter H2O)
This solution will be lasting 6 months but It will be covered by a black fabric/paper.
v Sulfuric acid solution :
Process :
It will be make 10% H2SO4 Solution.
Such as : 25 ml H2SO4 + 225 ml H2O
50 ml H2SO4 + 450 ml H2O
v Per-Oxide solution :
Process :
1.25 gm (Liquid) H2O2+ 250 ml H2O (5 gm/litter)
(Total volume will be 250 ml so water will less than 250 ml )
The solution will make in 250 ml volume metric flax.
Stapes :
1. 1.25 gm H2O2 will be taken by electric balance .
2. Than it will be transfer in 250 ml V.F
3. Than water will taken in flax border line so total volume will 250 ml
Test process :
1. H2O2 Solution 25 ml + H2SO4 Solution 25 ml in a konical flax. (0.125 gm H2O2 in total solution)
2. Burette will be fill by KMnO4 Solution .
3. KMnO4 Solution will added in (H2O2+ H2SO4 ) solution by drop and drop and flax will shak.
4. After change the (H2O2+ H2SO4 ) solution color (Slid pink) Burette will be stop.
5. And burette reading will be count. Example . 28 ml
Calculation
Formula :
= 51.68 %
But 0.1 Normal solution’s actual Normality 0.095 N
So correct purity is
= 49.096 %
NB:-Wight of sample = (25 ml* 5 gm) / 1000 ml
= 0.125 gm
Meqt. Of H2O2 = 34 amu / 2000
= 0.017
