Acell consists of a gold wire and a saturated calomel electrode (s. c.e.) in a 0.130 m auno 3 solution at 25 °c. the gold wire is connected to the positive end of a potentiometer, and the s. c.e. is connected to the negative end of the potentiometer. what is the half‑reaction that occurs at the au electrode? include physical states.

The half reaction occurring at this electrode will be given as:

Explanation:

In electrochemical cell reduction occurs at anode.

But the gold wire is connected to the positive terminal of the battery which means that gold wire will act as a cathode nad reduction will take place

The half reaction occurring at this electrode will be given as:

answer: h+ its less than oh

explanation:
