5. Two wires from a battery are tested with a piece of filter paper moistened with aqueous NaCl solution. The solution also contained phenolphthalein, an acid-base indicator that is colorless in acid and pink in base. When the wires touch the paper about an inch apart, the rightmost wire produced a pink color on the filter paper and the leftmost produced no color. Write balanced half-reactions for what is happening at each electrode. Be careful! NaCl (ag) is only there as a supporting electrolyte.
