a 1.0 L buffer solution is 0.250 mol L-1 CH3COOH and 0.050 mol L-1 CH3COOLi. Which of the following actions will exceed the capacity of the buffer? a)adding 0.050 moles of NaCl b)adding 0.050 moles of NH4Cl c)adding 0.050 moles of CH3COOLi d) adding 0.050 moles of CH3COOH e) adding 0.050 moles of HCl

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
