Consider the following. On the TV show Breaking Bad, an acid was attempted to be used to dispose of a body in a metal bathtub. However, the bathtub dissolved in the process. Many acids react in a redox reaction with metals to form H₂ gas, resulting in the dissolution of the metal. Which of the following metals, Fe(s), Cu(s), or Au(s) could the bathtub have been composed of on the show (assume the bathtub was composed of the pure metal, the acid used was HCI, and standard conditions)? a b Select an answer and submit.
