This lecture introduces the classification of chemical reactions into three main types: precipitation, acid-base, and oxidation-reduction. It explains the solubility of substances, the transfer of hydrogen ions in acid-base reactions, and the electron transfer in oxidation-reduction reactions. Examples are provided for each type, illustrating the formation of precipitates, the creation of hydronium and hydroxide ions, and the calculation of oxidation numbers. The lecture concludes with a summary of these concepts.
