The concentration of the copper half cell with 0.22 V is [tex]\rm \bold{5.7\;\times\;10^{-11}\;M}[/tex].
In the electrochemical cell, the reduction and oxidation takes place in different electrodes, and thereby it is termed as half cell. The standard cell potential of the given cell is 0 V.
The reduction potential of one half cell cathode is considered to be given as 1.6 mM. The cell potential is 0.22 V.
The potential of the half cell is given as:
[tex]\rm E=E^\circ_{cell}-\dfrac{0.059}{n}\;log\dfrac{anode}{cathode}\\\\0.22\;V=0-\dfrac{0.059}{2}\;log\dfrac{anode}{1.6\;\times\;10^-^3\;M}\\\\Anode\;conc.=5.7\;\times\;10^{-11}\;M[/tex]
The concentration of the copper half cell with 0.22 V is [tex]\rm \bold{5.7\;\times\;10^{-11}\;M}[/tex].
