Suppose you have two joined metals(Gold and Copper(II)) immersed in 1M HCl acid. Would actual corrosion happen? Why or Why not? Would actual corrosion occur if we start bubbling air into the solution? Why or Why not and provide cathode-anode half reactions?How fast is the corrosion occurring?Do we have enough information to answer this question? If not, what additional information is needed?
