<h3>What is the activity series?</h3>
The activity series is an arrangement of species in order of reactivity. The position of a specie in the series determines the possibility of certain reactions.
The following are the fates of these reactions;
- 2NaBr + I2--------->2NaI + Br2 - Not possible
- 2Fe + Al2O3 ----------> 2Al + Fe2O3 - Not possible
- 2AgNO3 + Ni ----------> Ni(NO3)2 + 2Ag - possible
- Pb + Zn(C2H3O2)2 ----------> Zn + Pb(C2H3O2)2 - Not possible
