A voltaic cell with Mn/Mn²⁺ and Cd/Cd²⁺ half-cells has the following initial concentrations: [Mn²⁺] = 0.090 M; [Cd²⁺] = 0.060 M(d) What are the equilibrium concentrations of the ions?

Respuesta :

The equilibrium concentration is 1.243×10^26

Ecell = 0 in equilibrium.

Ecell=E0cell-0.0591/n logK logK=Ecell- E0cell/-0.0591V/n logk=0V-0.7724V/0.0591/2

= 26.0946 K

=1026.0946 K

=1.2431026

when the Nernst equation is applied.

  • A galvanic cell, or voltaic cell, is an electrochemical cell that produces electricity by spontaneous redox reactions.
  • It is divided into two distinct half-cells.
  • A half-cell is made up of an electrode with a metal strip of M and a solution with Mn+ ions, where M can be any metal.
  • A voltaic cell is an electrochemical device that generates electricity through a chemical process.
  • Electricity is produced by a galvanic (voltaic) cell using the energy released during a spontaneous redox reaction (G0).
