london dispersion forces:) both iodine and hexane are non-polar meaning that the dominant IMF in each of them is the LDF. therefore the non-polar solute-non-polar solvent interaction would be LDF.

∙ 14y agoNon-polar bonds, or more specifically, temporary dipole-dipole bonds. The intermolecular forces in iodine (solid at room temperature) are considerably strong compared to the other halogens. These stronger bonds means that more heat energy is needed to break them, thus the melting and boiling points of iodine are higher.
The strength of the bonds is distinguished by the size of the element's molecules - fluorine has the smallest molecules, and iodine has the largest.

Explain the relative solubility of iodine in water?
Iodine itself, I2 is not very soluble in water. However, the solubility of iodine can be greatly increased by adding potassium iodide to the reaction. The potassium iodide is broken apart into K+ and I-. The potassium ion is then dissolved into the water, and the iodine ion reacts with the I2 to form I3-. This I3- molecule is soluble in water. Therefore, the solubility is relative because I2 is not very soluble, but I3- is soluble, and both are made of nothing but iodine. Hope this helps.
What is the role of potassium iodide in the formulation of strong iodine solution?
The role of KI in the preparation of strong iodine solution is to enhance the solubility of iodine crystals in water. Iodine is generally not soluble in water. The KI is added to help the iodine to be dissolved. -College Chemistry professor
Which substance acts an solvent in tincture iodine?
Because iodine is nonpolar, a nonpolar substance like ethanol would dissolve it. Iodine is insoluble in polar substances like water.
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.
Is hexane more dense than ethanol?
No, hexane is less dense than ethanol- hexane has a density of 0.6548g/mL and ethanol has a density of 0.789g/mL, so hexane will float on top of ethanol.
Solubility in hexane of period 3?
The period 3 trend of solubility in hexane is that solubility will increase as you move to the right of the period. Ionic bonds will not be soluble with hexane, but as the bonds become more covalent they will.
Does iodine dissolve in hexane?
water is a polar molecule, hexane is non polar. substances with like polarities mix, therefore the non polar iodine mixes with hexane and not water
Is 4-methylcyclohexanol solubility in hexane?
yes
Why iodine can be separated easily from sand?
Iodine is soluble in hexane.
How do you enhance the solubility of iodine?
The solubility of iodine in water is increased adding potassium iodide.
Arrange the substances in order of increasing solubility in hexane C6H14 CH2OHCH2OH C10H22 H2O?
hexane, ethanol, and water
What color will be if mixing iodine with hexane?
The color would be a yellowish-orange.
How do you separate iodine from sodium chloride?
Iodine is not contained in Sodium Chloride, so can not be removed from it. I am thinking you wish to separate a mixture of Iodine and Sodium Chloride. Heat the mixture to 114C and the iodine will melt. Iodine can be vaporized and distilled. Under certain conditions, Iodine can react with other chemicals to create unstable explosive compounds. So be careful out there.
How do you enhance the solubility of iodine in water?
To enhance the solubility of iodine in water, you can increase the temperature of the water as iodine is more soluble in hot water. Stirring or agitating the solution can also help by increasing the surface area and facilitating the contact between iodine and water molecules. Additionally, adding a solubility-enhancing agent like potassium iodide can significantly increase the solubility of iodine in water.
Is Ammonium chloride soluble in hexane?
Solubility is the property of a solute to dissolve in a solvent to form a homogeneous solution. The rule "like dissolves like" is used in terms of solubility. Urea is polar while hexane is non-polar, thus urea is not soluble in hexane.
How can you separate iodine from sodium chloride What is the process called?
Iodine can be separated by:- extraction with an adequate solvent, for ex. hexane- heating and evaporation
What is iodine solubility?
Iodine is highly soluble in water. It is also soluble in iodine solutions, chloroform, carbon tetrachloride and carbon disulphide among others.
