Additional info:Gold exists in two common positive oxidation states, +1 and +3. The standard reduction potentials for these oxidation states are

Au+ (aq) + e? ? Au(s) E?red = +1.69 V

Au3+ (aq) + 3e? ? Au (s) E?red = +1.50 V

Gold miners then react the basic aqueous product solution from part C with Zn dust to get gold metal. Write a balanced redox reaction for this process.
