The redox reaction Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s) takes place in which cell?
Answer & explanation
Correct answer: option 1
Daniell cell converts the chemical energy liberated during the redox reaction Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s) to electrical energy and has an electrical potential equal to 1.1 V when concentration of Zn2+ and Cu2+ ions is unity(1 mol dm–3). Such a device is called a galvanic or a voltaic cell.
