Chloride Ion is a chlorine anion that forms the negatively charged part of certain salts, including sodium and hydrogen chloride salts, and is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells.
Thus, \(\ce{NaCl}\) is the chemical formula for sodium chloride, which is a concise way of describing the relative number of different ions in the compound. A macroscopic sample is composed of myriads of NaCl pairs; each individual pair called a formula unit or empirical formula .
25 Σεπ 2022 · An ionic formula, like \(\ce{NaCl}\), is an empirical formula. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. Sodium sulfide, another ionic compound, has the formula \(\ce{Na_2S}\). This formula indicates that this compound is made up of twice as many sodium ions as sulfide ions.
The term chloride refers to a compound or molecule that contains either a chlorine ion (Cl −), which is a negatively charged chlorine atom, or a non-charged chlorine atom covalently bonded to the rest of the molecule by a single bond (−Cl).
Sodium chloride contains Na + and Cl - ions: this is one positive charge and one negative charge. the charges are balanced. so the formula is NaCl. Example 2. Magnesium oxide contains Mg 2+ and O...
Thus, NaCl is the chemical formula for sodium chloride, which is a concise way of describing the relative number of different ions in the compound. A macroscopic sample is composed of myriads of NaCl pairs; each pair called a formula unit.
