Cobalt Compounds and Acetate Ions

This video tutorial explains how to name the compound Co(CH3CO2)2. It begins by identifying Cobalt as a transition metal and the CH3COO group as the acetate ion. The tutorial then guides viewers through the process of naming the compound by first writing the name of the metal, Cobalt, followed by the polyatomic ion, acetate. Since Cobalt is a transition metal, the charge must be determined, which is shown to be 2+. The final name of the compound is Cobalt(II) acetate, with the Roman numeral indicating the charge of the Cobalt ion.
