Identify which of the following reactions are acid-base reactions and which are oxidation-reduction reactions.
a. For those which are redox reactions state which substance is oxidized and which is reduced.Be specific in your answers, for example distinguish between Zn(s) and Zn2+(aq).
b. For those which are acid-base reactions list the conjugate pairs and identify the acid and base members of each pair.
