Q46Short answer
Write the Nernst equation for the cell reaction in the Daniel cell. How will the ECell be affected when concentration of Zn2+ ions is increased?
Show answer
Zn + Cu2+ → Zn2+ + Cu 2+ V 0.059 [Zn ] ECell = E Cell – log 2+ 2 [Cu ] 2+ ECell decreases when concentration of Zn ions, [Zn2+] increases.
