Question

Two metals are used to make batteries. Would a battery in which both metals components are copper, make a good battery? Explain your reasoning.

Answer 1

Yes! the cell with electrodes made of copper, and a solution of \[\large CuS{O_4}\](copper sulfate) cab be a good battery, since the net free energy change is different from zero, more precisely, is:
\[\Delta G = - 5.706KJoules/mole\]
