The sodium carbonate removes the cuprous chlorides and neutralizes the hydrochloric acid in the pits. Sodium carbonate, unlike sodium sesquicarbonate, which is a double carbonate and acts as a complexing agent with copper, reacts relatively slowly with copper metal. Still, in come cases, slight alterations in the color of the patina can occur.

Reactivity series of metals | O Level Chemistry Notes

04/08/2020· Fe (s) + CuSO 4 (aq) → Fe SO 4 (aq) + Cu(s). When we drop iron into copper sulfate solution, a dramatic precipitation of reddish-brown copper occurs. At the same time, we form iron(II) sulfate, whereby iron has taken the place of copper. We say that iron has displaced copper from copper(II) oxide.. Fe(s) → Fe 2+ (aq) + 2e –. This happens because iron is more reactive than copper.
