Concept explainers
(a)
Interpretation:
A complete diagram of the galvanic cell has to be given.
Concept introduction:
Voltaic cell (or) galvanic cell:
Voltaic cell is an experimental setup used to generate
(b)
Interpretation:
The cathode and anode has to be labelled and the direction of flow of ions has to be indicated.
Concept introduction:
Voltaic cell (or) galvanic cell:
Voltaic cell is an experimental setup used to generate electric current through the spontaneous redox reaction. The voltaic cell is an electrochemical cell, which is converting a chemical energy into electrical energy. Cathode as the positive electrode. Anode as the negative electrode. Salt bridge is required. Ions are discharged only in cathode while anode is consumed.
(c)
Interpretation:
The balanced cell reaction has to be given.
(d)
Interpretation:
The shorthand notation has to be given.
Cell notation:
The shortest way for representing a certain electrochemical reaction is called as cell notation. The cathode and anode are separated through two bars or slashes representing a salt bridge, with anode present in the left and the cathode present on the right. Single bar is used to separate an individual solid, liquid or aqueous phases with each half-cell.
