Naming and Properties of Ternary Compounds: Sodium Nitrite, Potassium Chlorate, and More, Slides of Chemistry

Download Naming and Properties of Ternary Compounds: Sodium Nitrite, Potassium Chlorate, and More and more Slides Chemistry in PDF only on Docsity! Ternary Compounds Ternary Compounds Ternary compounds are those containing three different elements. (NaNO3, NH4Cl, etc.). The naming of ternary compounds involves the memorization of several positive and negative polyatomic ions, (two or more atoms per ion), and adding these names to the element with which they combine. i.e., Sodium ion, Na1+ added to the nitrate ion, NO3 1-, to give the compound, NaNO3, sodium nitrate. Binary rules for indicating the oxidation number of metals and for indicating the numbers of atoms present are followed. The polyatomic ions that should be learned are listed in a separate handout.
