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.

What id the solubility of potassium iodide at 30 degrees celcius?

The solubility of potassium iodide at 30 degrees Celsius is approximately 50 grams per 100 milliliters of water.


What is the use of potassium iodide in the preparation of iodine solution?

Potassium iodide is used in the preparation of iodine solution to increase the solubility of iodine in water. It helps stabilize the iodine in solution by forming triiodide ions, which prevents iodine from sublimating back to a solid state. Additionally, potassium iodide helps to maintain a consistent concentration of iodine in the solution.


What precipitate form when potassium iodide and lead nitrate react?

When potassium iodide and lead nitrate react, lead iodide precipitate forms due to the low solubility of lead iodide in water. This reaction is a double displacement reaction where the potassium and lead ions switch partners, resulting in the formation of the insoluble lead iodide.


How increasing the concentration of Potassium iodide and Sulfuric acid affects the speed of reaction?

Increasing the concentration of Potassium iodide and Sulfuric acid typically increases the rate of reaction. This is because higher concentrations provide more reactant particles, leading to more frequent collisions and a higher likelihood of successful collisions, which speeds up the reaction.


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.


What is solubility of iodide at 30 degres in 100 g h2o?

The solubility of iodide ions (I-) in water at 30 degrees Celsius is generally around 140 grams per 100 grams of water, depending on the specific iodide salt being considered (e.g., potassium iodide). This indicates that a significant amount of iodide can be dissolved in water at this temperature. However, for precise values, refer to solubility tables specific to the iodide compound of interest.


How the amount of potassium iodide added to the potassium iodate (V) solution in the conical flask affects the amount of iodine liberatedexplain.?

If more potassium iodide is added to the potassium iodate (V) solution in the conical flask, there will be more iodine liberated. This is because potassium iodide reacts with potassium iodate (V) to produce iodine. Therefore, increasing the amount of potassium iodide increases the rate of reaction and the amount of iodine generated.


What is the function of potassium iodide in iodometric titration?

Potassium iodide is used in iodometric titration as a source of iodide ions. It reacts with iodine to form triiodide ions, which are then titrated with a standard solution of thiosulfate to determine the concentration of the oxidizing agent.


What is the name of the binary compound formed from pottasium and iodine?
