What is the concentration of cu2 in the other half-cell? (assume the concentration in the unknown cell to be the lower of the two concentrations. )

Sagot :

The concentration of the copper half cell with 0.22 V is [tex]\rm \bold{5.7\;\times\;10^{-11}\;M}[/tex].

What is half cell?

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].
