I2 + Cl2 → 2 ICl.

Is iodine soluble in water?

Iodine dissolves easily in chloroform and hexane but does not dissolve in water.

Why is iodine slightly soluble in water?

Iodine does not dissolve in water because water is an extremely polar molecule, while iodine exists in the diatomic form of I2 , and is therefore non-polar, and will not dissolve in water. Ethanol has some polarity in its OH bond, but the C2H4 bond is non-polar, and therefore iodine has slight solubility in ethanol.

What type of intermolecular force of attraction is present in water?

There are three types of intermolecular forces: London dispersion forces (LDF), dipole- dipole interactions, and hydrogen bonding. Molecules can have any mix of these three kinds of intermolecular forces, but all substances at least have LDF.

Is ICl ionic or covalent?

Option a cannot be correct because ICl contains two nonmetal atoms and thus would be bonded covalently.

Which of the following bonds are polar?

Polar bonds form between any two dissimilar atoms that have different electronegativity values. C-Se, C-O, and N-H are polar, while Cl-Cl, O=O, are non-polar because they have identical bonded atoms. C-H is non-polar because the have negligible difference in electronegativity.

What is the electronegativity difference of ICl?

Dipole-dipole interactions will occur between molecules of ICl. The electrons in the molecule will be shared unevenly because Chlorine has an electronegativity of 3.0 and Iodine has an electronegativity of 2.5 The electronegativity difference is 0.5 (3.0-2.5 = 0.5).

What is 12.69 in iodine value formula?

Determination of iodine value

The iodine value was determined by the PORIM Test Method8. Iodine value was calculated as 12.69N (V2 – V1)/W where N=Normality of Na2 S2 O3 used, W=the Volume in millilitres of Na2S2O3 used (Blank), V1=the Volume in millilitres of Na2S2O3 solution used for the determination (test sample).

Why does the blank titration use more na2s2o3?

The more sodium thiosulfate required, the more saturated the oil is – which can be further proved that the “blank” solution has the most quantity of sodium thiosulfate titrated due to the fact that all iodine from iodine monochloride is not bonded and all become I2 molecules.
