Why iodine is not soluble in water




















It does not technically dissolve; rather, it forms a homogenous solution with water. Does iodine dissolve in vinegar? It was also concluded to be baking powder because of its chemical reaction to the acidity of the vinegar due to the mixture of baking soda it contained.

Iodine is a chemical indicator for starch and will turn purple if it is present in the substance 1 while vinegar is a common household liquid used for cooking.

Does iodine dissolve in vegetable oil? The reason the iodine molecules leave water to dissolve in oil is due to how polarity affects solubility.

Oil is non-polar; electrons in molecules of this substance are distributed evenly. Iodine is also a non-polar molecule therefore it is more soluble in oil; "like dissolves like".

Does iodine evaporate? Elemental iodine readily sublimes and is then rapidly lost to the atmosphere through diffusion. As in most chemical reactions, elevated temperature increases the rates of the reactions that form elemental iodine and increases the rate of evaporation of iodine. Can you drink iodine in water? Iodine is used to treat water to make it safe for drinking. You can buy iodine water purifying tablets that you add directly to water.

You can also buy water treatment cartridges for your home that have iodine in them. Some iodine will get into the water that you drink if you use these tablets or cartridges. Various gases such as O 2 , N 2 , H 2 , CO 2 are not very soluble because the gases are essentially non-polar.

Of course you may say that oxygen must be dissolved in water to sustain fish life -- true, but the solubility is very low. Carbon dioxide is soluble in water such as carbonated beverages -- again this is true but why does it fizz when opened or lose the bubbles on standing?

Carbon dioxide is not very soluble in water. Micelles and Detergents have many application of the solubility of polar and non-polar substances. Many large molecules both inside and outside of the cells, must literally navigate through a watery-aqueous environment. These are molecules of lipids and proteins may be largely non-polar. In order for these molecules to be soluble in water they must have some polar groups exposed to the water.

They dissolve in water in any amount. Starting with the four-carbon butanol the solubility of alcohols is starting to decrease.
