Galvanic Cells

What are electrochemical cells? How are they constructed? Explain the working of the different types of galvanic cells?

Write the chemical reactions used in the construction of the Daniel cell together with the half reactions.

What is a galvanic cell or a voltaic cell? Give one example.

Write the cell reaction and calculate the emf of the cell at $25°\mathrm{C}$

$Cr\left(\mathrm{s}\right)\left|{\mathrm{Cr}}^{3+}(0.0065\mathrm{M})\Vert {\mathrm{Co}}^{2+}(0.012\mathrm{M})\right|\mathrm{Co}\left(\mathrm{s}\right)$

${\mathrm{E}}_{\mathrm{Co}}^0=-0.280\mathrm{V}, {\mathrm{E}}_{\mathrm{Cr}}^0=-0.74\mathrm{V}$

What is $∆\mathrm{G}$ for the cell reaction?

A galvanic cell has electrical potential of $1.1 \mathrm{V}$. If an opposing potential of $1.1 \mathrm{V}$ is applied to this cell, what will happen to the cell reaction and current flowing through the cell?

Discuss briefly the function of the salt bridge in an electrochemical cell.
