Question 15 (5 points) (08.02 LC)
What happens to a glass of pure fruit juice when water is added to it? (5
O1) The number of moles of fruit juice increases.
O2) The number of moles of fruit juice decreases.
O3) The molarity of the juice increases.
O4) The molarity of the juice decreases.

The answer is c - the principal of original lateral continuity. 

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.
