Calcium Iodide
The net ionic equation for the dissolution of calcium iodide (CaI2) in water can be written as: CaI2 (s) → Ca2+ (aq) + 2I- (aq)
Ca(NO3)2 + 2KI ----> CaI2 + 2KNO3
The equation for the single displacement reaction between bromine and calcium iodide is: Br2 + CaI2 -> 2CaBr2 + I2
The balanced chemical equation for the reaction between bromine gas (Br2) and calcium iodide (CaI2) is 3Br2 + 2CaI2 → 2CaBr2 + 4I2. The reaction results in the formation of calcium bromide (CaBr2) and elemental iodine (I2).
The most common compound containing one calcium atom for every two iodine atoms is simply CaI2, or Calcium Iodide.
The ionic compound of CaI2 is calcium iodide. It is formed when calcium (Ca) and iodine (I) react to transfer electrons and create an ionic bond, resulting in the compound CaI2.
The oxidation state of iodine (I) in CaI2 is -1. In CaI2, calcium (Ca) has an oxidation state of +2, therefore two iodine atoms balance out the charge to form CaI2. Each iodine atom contributes a charge of -1 to achieve overall neutrality.
The chemical equation for the reaction between calcium and iodine is: Ca + I2 -> CaI2.
The net ionic equation for the dissolution of calcium iodide (CaI2) in water can be written as: CaI2 (s) → Ca2+ (aq) + 2I- (aq)
It is CaI2
Formula: CaI2
The pH of a solution of CaI2 would depend on the concentration of the solution. However, since CaI2 is a salt, it would dissociate in water to form Ca2+ ions and I- ions, which are not capable of directly affecting the pH of the solution. Therefore, the pH would mainly be determined by the autoionization of water.
The chemical formula of calcium iodide is CaI2. Written ionically: Ca2+(I-)2 or normally written as CaI2, without ionic charges.
