The elements. One mole of ethanol C, H,O is oxidized by potassium permanganate solution which
is acidified with sulphuric acid, forming ethanoic acid C, H,O,, if the percentage of
the actual yield is 60%, so what is the mass of ethanoic acid which can be actually
4
collected from the oxidation of 2.3 g of ethanol ?
a 1.32 g
b) 1.38 g
© 1.8g
(d) 3 g

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.
