What is the use of the KI in in the i2 in KI solution?
KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.
Is KI an ionic compound?
Potassium iodide (KI) forms an ionic bond. Potassium and iodine have very different electronegativities. The two atoms would form an ionic bond since ionic bonds form between atoms with a large difference in electronegativity (difference>1.7 using the Pauling scale will result in an ionic bond).

What is the molar mass of Al NO3 3?
Formula of the compound is Al(NO3)3. There are many different physical properties of this compound. For example, aluminum nitrate has molar mass which is equal to 212.996 g/mol. As for the density of the compound, it is 1.401 g/cm3.
Is KI I2 a homogeneous mixture?
The potassium iodide and the iodine that reacts with it increase the density of the phase. The solutions form a heterogeneous mixture.
Why is KI added in the preparation of iodine?
Molecular iodine is only slightly soluble in water. Adding potassium iodide to iodine in water rapidly converts the molecular iodine (I2) to the much more soluble triiodide ion (I3-).
Why is I2 more soluble in KI than water?
Iodine is covalent in nature and therefore, it does not dissolve in water which is polar. In KI solution, iodine reacts to form KI3 which is ionic in nature. Therefore, it becomes soluble in water.
What is the molar mass of ethanol c2h6o )?
The molecular formula C2H6O (molar mass: 46.07 g/mol, exact mass: 46.04186 u) may refer to: Dimethyl ether (DME, or methoxymethane) Ethanol.
Is KI a metal or nonmetal?
Potassium is in Group 1 of the Periodic Table. That means it is a metal. Iodine is in Group 17 of the Periodic Table. That means it is a nonmetal.
What is the element KI?
“KI” is the chemical symbol for potassium (“K”) iodide (“I”) on the Periodic Table of Elements.
What is the charge of KI?
Potassium Iodide’s Formula
Potassium iodide’s chemical formula is KI, where K is potassium and I is iodine. It is an ionic compound and each potassium ion has a charge of +1, while each iodine ion has a charge of -1.
How do you use KI paper?
- Remove one Potassium Iodide Starch test paper from the vial, being careful not to touch the paper anywhere other than where you grasp it.
- Dip the paper strip into the solution to be tested for 1-2 seconds.
- Remove the strip and shake off any excess liquid.
What is the role of KI in iodometric titration?
KI, or potassium iodide, is used in iodometric titration because the iodide will be oxidized to iodine in the presence of an oxidizing agent.
