Iodine Value of Activated Carbon
Apparatus:
Volumetric flask,
conical flask,
beaker,
burette,
pipette,
filter paper
Reagents:
* 0.1N Iodine solution ( 40 gm KI in 1 Ltr of Distilled water ).
* 0.05N Sodium Thiosulphate solution (12.5 gm Na2S2O3.5H2O in 1 Ltr Distilled water)
* 1% Starch solution
* Activated carbon
Procedure:
I Standardisation of Iodine solution
* Take 10c.c of 0.1N Iodine solution in conical flask.
* Add 2 drops of Starch solution.
* The pale yellow colour of Iodine Soln turns Blue.
* Titrate with 0.05 N Sodium Thiosulphate till it becomes Colourless.
* Burette reading corresponds to blank reading.(B)
II
* Weigh very accurately 0.2 gm of Activated carbon
* Introduce it into the Iodine flask which should be completely dry
* Add 40cc of 0.1N Iodine solution
* Shake the flask for 4 minutes and filter it
* Collect the filterate in a dry flask and Titrate 10cc of the filtrate against
Standard Sodium thiosulphate solution using starch as indicator
* Burette reading corresponds to (A)
Calculations:
Iodine value: C x Conversion factor; mg/gm
Factor:Mol wt. of iodine (127) x normality of iodine x 40 / Wt. of carbon x Blank reading
C=B-A This is dry basis test

Is Iodine more soluble in water or carbon disulfide?
carbon disulfide
What is the value of iodine?
The value of iodine is worth ?????????????? help im being spmaed by viruses?!↨☺‼○
What happens when iodine is added to carbon?
Not a lot. If the carbon was part of an unsaturated fat, it may break double bonds to join the fat (this is a test for unsaturation; by measuring how much iodine is absorbed we know how unsaturated the fat is). Otherwise, iodine is quite unreactive when introduced to carbon.
What is the pka value of iodine?
3.3
What is the meaning of MB value of activated carbon?
mb value of carbon is the methylene blue value of carbon.this indicates the decolo rising capacity of 0.1 g oof carbon.
What method is used to separate iodine from iron?
Use a magnet to attract and remove the iron filings.
What is the pH for activated carbon?
Activated carbon hasn't a pH.
Why activated carbon is called activated?
Activated carbon has high surface area; this characteristic improve the reactivity of the material.
Are graphite and iodine metalloids?
No. Graphite is a form of carbon, and iodine is a halogen, and both carbon and iodine are nonmetals.
What elements are carbon sulfur and iodine?
carbon is C,sulfur is S,and iodine is I
What will happen if activated carbon mixed with water?
when activated carbon react with water it form carbon mono oxide
What does the company Calgon Carbon offer?
