Question

what is standard electrode potential​

Answer 1

Answer:

standard electrode potential is defined as the measure the individual potential of reversible electrode at standard state with ions at an effective concentration of 1mol dm-3 at the pressure of 1 atm.

The basis for an electrochemical cell, such as the galvanic cell, is always a redox reaction which can be broken down into two half-reactions: oxidation at anode (loss of electron) and reduction at cathode (gain of electron). Electricity is generated due to electric potential difference between two electrodes.

Answer 2

Answer:

It is defined as the potential difference developed between metal electrode and solution of ions at 1 bar pressure and 25°C temperature
