Conservation of Atoms

Mr. Anderson explains the conservation of atoms in chemical reactions, emphasizing that matter is neither created nor destroyed. He introduces gravimetric analysis and titration as methods to determine unknowns in reactions. Gravimetric analysis involves using the mass of a product to find the analyte, while titration uses a chemical indicator to find the equivalence point. The video concludes with a recap of these concepts.
