[Chemistry Class Notes] on Iodide Formula Pdf for Exam

In chemistry, ionic compounds are composed of ions that are held together with electrostatic forces. This is called an ionic bond. These ions gain or lose electrons as atoms. Ionic compounds made up of positively charged ions are neutral compounds called cations and negatively charged ions are called anions. The compounds are named in a format that the first cation name is written then followed by anion name. For example, NaCl is an ionic compound that contains a cation Na⁺ and an anion that is Cl–.

Iodide Chemical Formula 

The iodide formula is also known as the Iodide anion formula contains a compound I^– with a -1 oxidation state. It is the greatest monatomic anion. The radius is 206 picometers approximately. The chemical or molecular formula of Iodide is I^–. The most common iodide lately known is Iodargyrite. Idargyrite is natural crystalline silver iodide. Copper, lead, and mercury are found combined with iodide anions. The mercury, lead, iodide reacts with oxygen and produces iodide. They also act as a mild reducing agent. 

Barium Iodide Formula

Barium iodide has the formula BaI2 and is an inorganic compound. The compound exists as a white solid containing an anhydrous and hydrate. The anhydrous salt is produced when hydrated barium iodide is heated. It is soluble in water, ethanol, and acetone freely. Each Barium centre bounded with nine iodide ligands representing lead(II) chloride. It has a similar structure to BaCl2, a crystalline packing structure. Organobromine compound is made when the Barium Iodide formula reacts with the potassium compound of alkyl. To produce a highly active form of barium metal barium iodide is reduced to lithium biphenyl.

Calcium Iodide Formula

The ionic compound of Calcium and Iodine is called the Calcium Iodide formula. It is highly soluble in water. The calcium iodide salt is colourless in nature. It has properties of the salts like calcium chloride. Its application is done in photography. It is also mixed with cat food. It provides iodine to the cats. Reducing calcium iodide with pure sodium metal:

CaI2+2 Na => NaI + Ca

Conclusion

Iodide formulas are an important part of chemistry. If you study this portion of chemistry thoroughly then a good score can be achieved. Chemistry is a scoring subject and organic chemistry makes it much more fun to learn.
