A student is electroplating a silver spoon using aqueous silver nitrate and a pure silver electrode connected as the anode.
Which statement correctly describes what happens to the silver electrode during electroplating?
Which statement correctly describes what happens to the silver electrode during electroplating?
- It loses mass because silver atoms form Ag ions and go into solution.
- It gains mass because Ag ions are deposited onto it.
- Its mass stays the same because no reaction occurs at the anode.
- It turns into silver oxide without any change in mass.
