The video explains the reaction of lithium carbonate (Li2CO3) with water (H2O). It discusses the solubility of lithium carbonate, which is slightly soluble, meaning some of it dissolves in water while most remains solid. The video uses a solubility table to illustrate this point. It then details how to write the chemical equation for the dissolution of lithium carbonate in water, emphasizing the formation of lithium ions (Li+) and carbonate ions (CO3 2-). The video concludes with a note on the implications of the solubility table's findings.
