1 decade ago. You can view more details on each measurement unit: molecular weight of Calcium Iodide or mol The molecular formula for Calcium Iodide is CaI2. yes. Iodide is the ion form of iodine, occurring when iodine bonds with another element, such as potassium. What are the products of this reaction ? Calcium iodide can be formed by treating calcium carbonate, calcium oxide, or calcium hydroxide with hydroiodic acid: CaCO 3 + 2 HI → CaI 2 + H 2 O + CO 2. Calcium and iodine is bonded with an ionic bond to form calcium iodide, CaI2. Hydrate or anhydrous forms may be purchased. Iodide compounds are used in internal medicine. At this state, calcium is quite unstable. Mercury (l) nitrate and Calcium Iodide ==> Mercury (I) iodide + Calcium … Problem Solving| IONIC COMPOUND - Calcium iodide Step 1 (Atoms involved) Step 2 (Chemical symbol) Step 3 (Formed Ion) Step 4 (Criss-cross multiply the charges) Step 5 (Remove the plus sign to determine the chemical formula) We assume you are converting between grams Calcium Iodide and mole. The name of a metal ion is the same as the name of the metal atom from which it forms, so Ca 2+ is called a calcium ion. 1 Answer. It has 2 valence electrons as you can see. What is IODIDE? When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same number of electrons as an atom of the next noble gas in the periodic table. Calcium has 20 electrons (electron arrangement of 2.8.8.2). The chemist can form this compound by using anyone out of calcium oxide, calcium carbonate or calcium hydroxide with hydrochloric acid. 1 grams Calcium Iodide is equal to 0.003402669067227 mole. Iodide is the salt, which could for example, be iodine combined with calcium or potassium, and can be found in seaweed sources and mineral deposits. Calcium iodide slowly reacts with oxygen and carbon dioxide in the air, liberating iodine, which is responsible for the faint yellow color of … Image Transcriptionclose. Calcium Iodide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. However, the formula for calcium iodide is #CaI_2# - there are 2 iodine ions present. calcium nitrate...is that right ? Therefore, the calcium atom transfers 2 valence electrons, one to each iodine atom, to form the ionic bond. We will discuss the Calcium Iodide formula along with its … Answer Save. The name of a monatomic cation is simply the name of the element followed by the word ion.Thus, Na + is the sodium ion, Al 3 + is the aluminum ion, Ca 2 + is the calcium ion, and so forth.. We have seen that some elements lose different numbers of electrons, producing ions of different charges (Figure 3.3). Aqueous solution of Mercury (l) nitrate and calcium iodide are mixed. Naming Ions. Treating an iodide with manganese dioxide and sulfuric acid sublimes the iodine. Calcium Iodide is an inorganic compound made of calcium and iodine elements. Relevance? Structure, properties, spectra, suppliers and links for: Calcium iodide, 10102-68-8. This makes sense because the iodine ion has a charge of -1, so two iodine ions have to be present to cancel out the +2 charge of the calcium ion. The SI base unit for amount of substance is the mole.
