Hi,In a galvanic/voltaic cell when you have an electrode like copper or anything like that, then the salt solution that it dips into..can it be any copper salt like CuSO4, or CuCl2??Is it the same in electrolytic cells?

DEAR STUDENT,

The redox reaction in a galvanic cell is a spontaneous reaction. For this reason, galvanic cells are commonly used as batteries. Galvanic cell reactions supply energy which is used to perform work. The energy is harnessed by situating the oxidation and reduction reactions in separate containers, joined by an apparatus that allows electrons to flow. A common galvanic cell is the Daniell cell, shown below.
