Standard cell potentials

Complete the diagram at the right by filling in the formulas for the composition of the electrodes and of the ions in the solutions. Place these formulas near the arrows leading into the solutions. Also indicate at the top which electrode is the anode and which electrode is the cathode.

What constitutes an electric current in a wire?

Free $e^{-}$conspaters and

Electre current in a wrre

Indicate the direction of these particles by drawing an arrow over the wires connected to the voltmeter.

What constitutes an electric current in a solution?

freel moreut of ions

Indicate the direction of movement of these particles in the solution by writing their formulas on the proper arrow below the sketch.

Why must the two solutions come into actual contact?

$To$ Campete the Circuit $$

$q,v_{(92)}^{2+}+2e^{-}Cu(5)$

Write the half$-$reaction taking place at the anode.

$Z_{(s)}{Z}_n^{2+}(a)+2e^{-}$

Write the half$-$reaction taking place at the cathode.

Write the total cell reaction.

$z^{{?}^{?}}(s)+u^{2+}(aq)-u^{2+}(eq)$
