Explain Ionic Compounds
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.
FAQs on Iodide Formula
1. Write the Difference Between Magnesium Iodide and Silver Iodide?
Ans: Diiodo Magnesium formula is also known as magnesium iodide formula. Various hydrates are present in the compound that are halides and are insoluble in water. MgI2(anhydrous) is the chemical formula or molecular formula of Magnesium Iodide. When magnesium oxide, magnesium carbonate, and magnesium hydroxide are treated with hydroiodic acid it produces magnesium iodide formula. Silver Iodide Formula is AgI and is an inorganic compound. It contains impurities of metallic silver that provide a grey colouration making it a bright yellow solid. As AgI is highly photosensitive silver contamination arises. This property is used in silver-based photography. With the reaction of silver ion and iodide solution Silver iodide is formed.
2. Explain the Lead Iodide Formula and Why it is Hazardous?
Ans: Plumbous Iodide formula is also known as Lead Iodide formula. Its stability is very poor, and it is a highly toxic salt. Pbl2 is the molecular or chemical formula of Lead Iodide. It is bright yellow at room temperature and remains in a solid form. The colour changes to reddish-orange when further heated at a higher temperature. It is insoluble in water and has no odour and its density is more than water.
Safety measures:
It is dangerous and hazardous for the environment and green nature.
It is carcinogenic for human health and can lead to death and harmful for animals also.
3. Explain Briefly the Properties of the Zinc Iodide Formula?
Ans: Zinc iodide is made by the combination of zinc and iodide. Its chemical formula or molecular formula is ZnI2. It can absorb water easily from the atmosphere and is a white solid in shape and structure. By refluxing ether it can be directly manufactured with zinc and iodine. Zinc iodide appears as a white powder. Its melting point is 446-degree Celsius. Its boiling point is 1150-degree celsius. The density of zinc iodide is 4.74 gm/cm3. The molar mass of zinc iodide is 319.22 gm/mol. It is used in electron microscopy, industrial radiography, and also used as a catalyst.
