Chlorine anion name

Thought process. Bromic acid corresponds with the memorized -ic acid, chloric acid, HClOj. The acid and ion formulas come from substituting Br for Cl in the corresponding chlorine formulas. The anion name for an -ic acid is the name of the central element changed to end in -ate. 

The bleaching process, in contrast, poses major difficulties. Traditional paper bleaching uses chlorine gas, which is reduced to chloride anions, cr, as it oxidizes the colored pigments in wood pulp. The chloride anion is not a pollutant, as it is a major species in the oceans. Unfortunately, chlorine processing also generates small quantities of chlorine-containing dioxins such as 2,3,7,8-tetrachloro-dibenzo-p-dioxin, whose stmcture (below) appears less formidable than its name ... 

Oxyanions consist of an atom of an element plus some number of atoms of oxygen covalently bonded to it. The name of the anion is given by the name of the element with its ending changed to either -ate or -ite. In some cases, it is also necessary to add the prefix per- or hypo- to distinguish all the possible oxyanions from one another. For example, there are four oxyanions of chlorine, which are named as follows ... 

Nciming a simple ionic compound is easy. You pair the name of the cation with the neune of the anion and then change the ending of the anion s ncime to -ide. The cation always precedes the anion in the final name. For example, the chemical name of NaCl (a compound made up of one sodium atom and one chlorine atom) is sodium chloride. 

If the name of the anion begins with a vowel, you drop the o in hydro- to avoid having two vowels next to each other. The anion in this case is chlorine, so you write hydrochlorine. 

This reaction, inaptly named condensation reaction43, proceeds either by a nucleophilic substitution mechanism or by insertion of dichlorogermylene into the C—Cl bond. The nucleophilic substitution mechanism is doubtful. In accordance with quantum-chemical calculations, the negative charge in the anion GeCh- is distributed on chlorine atoms and a movement of anion to the cation from the rear results in Cl- loss and GeCl2 formation39. 

When writing a chemical formula, you learned that you write the metal element first. Similarly, the metal comes first when naming a chemical compound. For example, sodium chloride is formed from the metal sodium and the non-metal chlorine. Think of other names you have seen in this chapter, such as beryllium chloride, calcium oxide, and aluminum oxide. In each case, the metal is first and the non-metal is second. In other words, the cation is first and the anion is second. This is just one of the rules in chemical nomenclature the system that is used in chemistry for naming compounds. 

A binary compound is an inorganic compound that contains two elements. Binary compounds may contain a metal and a non-metal or two non-metals. Binary compounds are often ionic compounds. To name a binary ionic compound, name the cation first and the anion second. For example, the compound that contains sodium and chlorine is called sodium chloride. 

Iodine is produced by similar methods, namely, oxidation of the iodide anion from brines by chlorine. However, iodine is also produced in a reductive process by reacting NalOs, extracted from the natural source of Chilean saltpeter, with sodium hydrogen snffite. The pentavalent iodine is reduced to iodide (equations), which is then treated and oxidized with a sufficient amonnt of the mother liquor to liberate elemental iodine (equation 5). In contrast to chlorine and bromine, which have large industrial uses, iodine has no predominant commercial use. 

The oxygen acids of chlorine and their anions have the following formulas and names ... 

With the addition of one electron, chlorine becomes an anion, which is another name for a negative ion. To designate an anion, the ending -ide is added to the root name of the element. Thus the anion of chlorine is called the chloride ion. What is the name of the anion formed from nitrogen ... 

Many ionic componnds are binary compounds, or compounds formed from just two elements. For binary componnds the first element named is the metal cation, followed by the nonmetallic anion. Thus NaCl is sodium chloride. The anion is named by taking the first part of the element name (chlorine) and adding -ide. Potassium bromide (KBr), zinc iodide (Znl2), and aluminum oxide (AI2O3) are also binary componnds. Table 2.2 shows the -ide nomenclature of some common monatomic anions according to their positions in the periodic table.
