What is the pka value of iodine?
3.3
Significance of iodine value?
iodine value is basically used to determine the quality of any unsaturated oils on the basis of how much is the shelf life of that particular oil. -#@sh..!
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
What is the difference between iodine crystals and iodine solution?
Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
What is a solute in tincture of iodine?
The solute in tincture of iodine is iodine.
Which element has a higher electronegativity value Rubidium or Iodine?
Iodine
What is the pka value of iodine?

Is iodine a positive or negative charge?
No, nitrogen is more electronegative than iodine. Electronegativity of nitrogen= 3.04 Electronegativity of Iodine = 2.66
What does a high iodine value mean?
shorter shelf life of oil
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
How do you prepare Wijs solution from iodine monochloride vial for determining the iodine value of a fatty acid?
Wijs solution is iodine monochloride (ICl) dissolved in acetic acid.For a detailed recipe see this link.
What is the value of distribution coefficient of iodine between water and chloroform?
For Iodine in Chloroform & water, the distribution ratio is 250; hence at equilibrium, the iodine concentration in the chloroform phase is 250 times then in the water phase.
How is iodine estimated in ccl4 and h2o layer?
Titrate each solution separately with solution of known concentration of sodium thiosulphate. The titre value will give the amount of thiosulphate reacted with iodine, hence you can find concentration of iodine.
