Redox Introduction
... Since there is no change in the charge of these ions in the reaction, there are no electron changes. This reaction is not an oxidation-reduction reaction. The production of a (BaS04) is nearly always a result of a non-redox reaction. Most acid-base reactions are also the non-redox type. Since nearly ...
