Identify the location of oxidation in an electrochemical cell. identify the location of oxidation in an electrochemical cell. the electrode the anode the cathode the salt bridge the socket submit

Respuesta :

Answer is: the anode.
An electrochemical cell (galvanic cell) is generating electrical energy from chemical reactions.
In galvanic cell specie(for example zinc and zinc cations)  from one half-cell lose electrons (oxidation) and species from the other half-cell (for example copper and copper cations) gain electrons (reduction).
Oxidation on zinc anode: Zn(s) → Zn²⁺(aq) + 2e⁻.

The location of oxidation in an electrochemical cell: the anode

Further explanation

Voltaic cells or also called galvanic cells are electrochemical cells that produce electrical energy due to redoxs reactions / chemical reactions.

Electric current is generated due to the flow of electrons from the anode that undergoes an oxidation reaction to the cathode which has a reduction reaction in the circuit of an outer wire circuit

The parts of a voltaic cell are:

  • Cathode : reduction occurs, a positive pole
  • Anode: oxidation occurs, a negative pole
  • Electrolytes: an electrically conductive solution on both electrodes
  • Conductor wire: the link between the cathode and the anode
  • Salt bridge: as neutralizing anions and excess cations of electrolyte solution (supplying anions to the anode and cations to the cathode; for example KNO₃ solution)

In the electrolytic cell the positive pole - the anode whereas the negative pole - the cathode

Both of these electrochemical cells (volataic cell and electrolytic cell) still show that oxidation reactions occur at the anode despite different signs
