What are some examples of ternary ionic compounds?

When more than one polyatomic ion is present in a compound, the formula of the ion is placed in parentheses with a subscript outside of the parentheses that indicates how many of those ions are in the compound. In the last example above, there is one Fe3+ cation and three OH- anions. read more

Ternary compounds are composed of three different elements. The most common types of ternary compounds consist of a metallic cation (positive ion) and a polyatomic anion (negative ion). The only common polyatomic ion with a positive charge is the ammonium ion. read more

A ternary ionic compound is an ionic compound composed of three or more elements. In a typical ternary ionic compound, there is still one type of cation and one type of anion involved. The cation, the anion, or both, is a polyatomic ion. read more

Like all ternary compounds, ternary acids consist of three elements, one of which is hydrogen and the other two are combined in the form of a complex ion. Like binary acids, these compounds are not named as acids unless they are in aqueous solution, as indicated by the symbol (aq). read more
