Calcium hydroxide is ionic, and therefore polarity does not occur.
It is CaI2
Formula: CaI2
Calcium Iodide
The chemical formula i2Ca is incorrect because the element symbol "i" is not recognized in the periodic table. The correct chemical formula for calcium iodide is CaI2, where calcium has a +2 charge and iodine has a -1 charge.
Calcium Iodide, CaI2, contains calcium, Ca and iodine, I.
It is about in between ionic and polar bond in CaI2.Almost every, but not all, metals bonding to non-metals bond ionic, but if the difference of electronegativity (E.N.) is smaller than 1.2 than it tends to polar.So CaCl2 is ionic (diff.E.N. 1.79) and CaI2 is somewhat polar (diff.E.N. 1.17)
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.
