In this episode, we discuss the neutralisation of acids. Neutralisation reactions involving acids are explored in this source, which explains how acids react with different types of bases. Specifically, it outlines the reactions of acids with metal carbonates, metal oxides, and metal hydroxides. For each base type, a general equation is provided al…
