Cobalt Compounds and Bicarbonate Ions

The video tutorial explains how to name the compound Co(h33). It starts by identifying Cobalt as a transition metal and recognizing HCO3 as a polyatomic ion, known as bicarbonate or hydrogen carbonate. The tutorial then discusses the need to determine the charge of Cobalt, which is 3+, to balance the three 1- charges of the bicarbonate ions. The final name is Cobalt 3 bicarbonate, with the Roman numeral indicating the charge of Cobalt.
