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.
(I) 3 HNO2(aq)<--->HNO3(aq) + 2 NO(g) + H2O(l)
(II) HNO3(aq) + (CH3)2NH(aq)<--->NO3(aq) + (CH3)2NH2+(aq)
(III) 2 HBr(aq) + Cl2(aq)<--->2 HCl(aq) + Br2(aq)
(IV) CCl3COOH(aq) + HCO2<--->CCl3CO2-(aq) + HCO2H(aq)
