2.538g in 1000ml.
If you are making this for a titration, like for SO2 or thiosulfate, you need also to add iodide:
1. dissolve 8 g potassium iodide in about 250 mL water.
2. add 2.538 g iodine to the water solution. Stir until dissolved.
3. transfer to a 1000 mL volumetric flask and Q.S. to 1000 mL
You should standardize vs. thiosulfate or arsenious oxide.

What is the reason behind using 40 g of potassium iodide and 12.7 g of iodine to prepare 0.1 N of iodine?
- The atomic weight of iodine is 126,90447; for a 0,1 N solution, dividing by 10 the result is 12,69. - The iodide (KI) is added to increase the solubility of iodine in water or alcohol.

What is Iodine value for Activated Carbon?
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 From Ishan Udyog Bhilai
What is the chemical name for Nitrogen Hydrogen and Iodine?
if by chemical name you mean element then: Nitrogen = N Hydrogen = H Iodine = I
Equation used to determine the iodine value?
Iodine value= (B-S)N x 12.69 ------------------- wt of sample where, B=titration of blank S= titration of sample N= normality of thiosulphate
