Understanding Acetate and Calcium Compounds

The video tutorial explains how to write the name for Ca(CH3COO)2, also known as calcium acetate. It begins by introducing the acetate ion and its alternative representation, C2H3O2. The tutorial then guides viewers through naming the compound by first identifying the metal, calcium, using the periodic table, and then recognizing the polyatomic ion, acetate. The video emphasizes the importance of memorizing or referencing a table of polyatomic ions to identify acetate. Finally, the tutorial concludes with the complete formula for calcium acetate and a thank you from Dr. B.
