WebThe driving force for this metathesis is the removal of ions from solutions. Salt metathesis is also known as precipitation reaction. General Reaction for Salt Metathesis A-B + C-D → A-C + B-D (ppt.) Example: Aqueous solutions of silver nitrate (AgNO 3) and sodium chloride (NaCl) reacts to give sodium nitrate (NaNO 3 ). Webdriving force for all corrosion is the lowering of a system’s Gibbs energy. As Fig. 1 illustrates, the production of almost all metals (and engineering components made of metals) involves adding energy to the system.
