Why is iodine slightly soluble in water while lactose is very soluble?
Iodine is slightly soluble in water due to its nonpolar molecular structure, which limits its interaction with polar water molecules. In contrast, lactose, a disaccharide composed of glucose and galactose, has multiple hydroxyl (-OH) groups that can form hydrogen bonds with water, making it highly soluble. The polar nature and hydrogen-bonding capability of lactose enhance its solubility compared to iodine.
Is iodine more soluble in mineral oil or water?
Iodine is more soluble in mineral oil than in water. This is because iodine is a nonpolar molecule, and mineral oil is also nonpolar, allowing for better solvation. In contrast, water is a polar solvent, which does not effectively dissolve nonpolar substances like iodine. Thus, iodine's solubility is significantly higher in mineral oil.
How do you enhance solubility of solid fertilizers?
You can enhance the solubility of solid fertilizers by grinding them into finer particles, adding them to warm water, stirring continuously, and adjusting the pH of the solution if necessary. Additionally, using chelating agents or surfactants can also help improve solubility.
Is the largest amount of iodine dissolved in 100cm3 of water at room temperature?
The solubility of iodine in water is around 0.3 g per 100 mL of water at room temperature, making it the maximum amount that can dissolve under those conditions.
Strychnine solubility in water?
Strychnine solubility in water is 0,02 % at 20 oC.
How do you enhance the solubility of iodine?
To enhance the solubility of iodine, you can use solvents like ethanol, acetic acid, or potassium iodide solution. These solvents can help dissolve iodine more effectively due to their polar nature. Additionally, increasing the temperature or agitation can also improve the solubility of iodine in a solvent.
Do water and iodine form a solution?
Iodine is very low soluble in water; adding potassium iodide the solubility is higher.
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
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 happens when you add iodine to water?
Nothing special happens and no reaction occurs. Iodine is hardly soluble in water.
Is iodine soluble?
It is a little but i have no idea!!
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.
What is characteristics of iodine crystal that make it soluble to water?
Iodine crystals are soluble in water due to the formation of a complex between iodine molecules and water molecules called the I3- ion. This ion increases the solubility of iodine in water by enhancing its ability to dissolve and form a solution. Additionally, the polar nature of water molecules allows them to interact with the polar iodine molecules, facilitating their dissolution.

Iodine is more soluble in mineral oil than in water. This is because iodine is a nonpolar molecule, and mineral oil is also nonpolar, allowing for better solvation. In contrast, water is a polar solvent, which does not effectively dissolve nonpolar substances like iodine. Thus, iodine's solubility is significantly higher in mineral oil.
Why is water a poor solvent for the recrystallisation of iodine?
Water is a poor solvent for the recrystallization of iodine because iodine is only slightly soluble in water. As a nonpolar solvent, water cannot effectively dissolve the polar iodine molecules, resulting in low solubility and poor recrystallization efficiency. Other solvents, such as ethanol or acetone, are more suitable for recrystallizing iodine due to their ability to dissolve iodine more effectively.
Why the solubility of iodine in water increases as the concentration of potassium iodide increases?
The I2 molecules in iodine are not very soluble in water because they are not alike. I2 is non-polar whereas H2O is polar. But KI solution contains I- ions which combine with the I2 molecules to form I3- ions because these are charged they dissolve in the water which is a polar solvent. by tarun das
