For the following electrochemical cell, which of the following statements is true when the cell operates spontaneously? (That is, when e are allowed to flow whichever way they "want" to)? Al(s) Pt(s) 1 M Al(aq) 1 M CIO3(aq) 1 M CIO2 (aq) 1 MOH(aq) 1. The measured voltage would be 1.99 V 2. The measured voltage would be 1.33 V 3. The Pt electrode would be the anode 4. Electrons would move from right to left (---)

1. The measured voltage would be 1.99 V 2. The measured voltage would be 1.33 V 3. The Pt electrode would be the anode 4. Electrons would move from right to left (<---) o 2 and 3 only o 1 and 4 only o 1 only o 1 and 3 only O 2 and 4 only
