Ternary compound

From Wikipedia, the free encyclopedia

In chemistry, a ternary compound is a compound containing three different elements. An example of this is sodium phosphate, Na₃PO₄. The sodium ion has a charge of 1+ and the phosphate ion has a charge of 3-. Therefore, three sodium ions are needed to equal one phosphate ion. Another example of a ternary compound is calcium carbonate (CaCO₃).
