Assigned as Homework ? HQ18.26 A voltmeter attached to the voltaic cell constructed in the previous question registers a positive voltage of 1.677 ± 0.020 V. Enter the correct chemical symbol of the unknown metal in this voltaic cell. (Use Table 18.3 for your standard cell potentials Reduction Reaction Potential (e) Volts 3.053 2.866 1.692 1.645 1.498 1.358 1.229 1.156 0.957 0.800 0.342 0.247 AgAg

Solution

A voltaic cell constructed

gave a voltage = 1.677 V

SHE electrode has potential of 0

So,

the correct chemical symbol of the unknow metal = Au
