Q
What are the components of an electrochemical cell?
A
- electrode (2)
- doors to the cell
- allows e- to enter and exit the cell
- Electrolyte
- medium that allows e-/ions to move thru
- Salt bridge/semi-permeable membrane (galvanic cell)
- role is to keep the cell neutral
- Power source (electrolytic cell)
- supplies power to cell
