Examples: nitrate ion (NO 3-) + H + (denoting formation of acid) = nitric acid (HNO 3) If the ion ends in -ite and is added with an acid, then the acid name will have an -ous ending.
Naming Ions. 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 "Predicting Ionic Charges ...
20 maj 2018 · Naming Ions. 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).
For these ions, the name of the element followed by the term ion is an unambiguous name. For example, the sodium ion can only be Na +, the calcium ion only Ca 2+. According to IUPAC rules, the names of all other metallic cations contain the name of the element followed by its oxidation state (in parentheses) in that ion.
For example, the systematic name for KNO 3 is potassium nitrate, but its common name is saltpeter. In this text, we use a systematic nomenclature to assign meaningful names to the millions of known substances.
It is a readily available source of the nitrate anion (NO 3−), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics, smoke bombs and other explosives, glass and pottery enamels, food preservatives (esp. meats), and solid rocket propellant.
The NO 3- ion, for example, is the nitrate ion. The prefix hypo - is used to indicate the very lowest oxidation state. The ClO- ion, for example, is the hypochlorite ion. The prefix per - (as in hyper-) is used to indicate the very highest oxidation state. The ClO 4- ion is therefore the perchlorate ion.
