Sodium phosphate, Na 3 PO 4, is a ternary compound. An example is sodium phosphate, Na 3 PO 4. The sodium ion has a charge of 1+ and the phosphate ion has a charge of 3–. Therefore, three sodium ions are needed to balance the charge of one phosphate ion. Another example of a ternary compound is calcium carbonate, CaCO 3. In naming and writing ...
This can be dependent on the size, charge, or structure of the ions. Common examples of ions that can bind to ion exchangers are: H + and OH − . Singly charged monatomic (i.e., monovalent) ions like Na +, K +, and Cl −. Doubly charged monatomic (i.e., divalent) ions like Ca 2+ and Mg 2+. Polyatomic inorganic ions like SO 2− 4 and PO 3− 4.
Solubility of salts in organic solvents is a function of both the cation and the anion. The solubility of cations in organic solvents can be enhanced when the anion is lipophilic. Similarly, the solubility of anions in organic solvents is enhanced with lipophilic cations. The most common lipophilic cations are quaternary ammonium cations ...
For example the chloride anion, Cl − becomes chlorido. This is a difference from organic compound naming and substitutive naming where chlorine is treated as neutral and it becomes chloro, as in PCl 3, which can be named as either substitutively or additively as trichlorophosphane or trichloridophosphorus respectively.
The colour of a salt is often different from the colour of an aqueous solution containing the constituent ions, [80] or the hydrated form of the same compound. [13] The anions in compounds with bonds with the most ionic character tend to be colorless (with an absorption band in the ultraviolet part of the spectrum). [81]
Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
In chemistry, ion association is a chemical reaction whereby ions of opposite electric charge come together in solution to form a distinct chemical entity. [1] [2] Ion associates are classified, according to the number of ions that associate with each other, as ion pairs, ion triplets, etc. Ion pairs are also classified according to the nature of the interaction as contact, solvent-shared or ...
Ternary metal hydrides have the formula A x MH n, where A + is an alkali or alkaline earth metal cation, e.g. K + and Mg 2+. A celebrated example is K 2 ReH 9, a salt containing two K + ions and the ReH 9 2− anion. Other homoleptic metal hydrides include the anions in Mg 2 FeH 6 and Mg 2 NiH 4.
