The qualitative analysis scheme contains a vast array of reactions involving precipitation, formation of coordination complexes and oxidation-reduction. Identify each of the following as primarily one of the above kinds of reaction.
a)Zn2+(aq) + 4 NH3(aq) ------> Zn(NH3)42+(aq)
b)Co(H2O)62+(aq) + 4 SCN-(aq) -----> Co(SCN)42-(aq) + 6 H2O
c)2 Mn2+ + 5 BiO3- + 14 H+ -----> 2 MnO4- + 5 Bi3+ + 7 H2O
d)2 Co(OH)3 + H2O2 + 8 H+ -------> 2 Co2+ + 8 H2O
e)3 Zn2+ + 2 K+ + 2 Fe(CN)64- ----> Zn3K2[Fe(CN)6]2
