Question 10 GCE_MODEL_QUESTIONS_VOL1 • 2025 • CHEMISTRY • essay

A galvanic cell is constructed using a copper electrode immersed in 0.10 M Cu²⁺ solution and a silver electrode immersed in 0.010 M Ag⁺ solution. The standard reduction potentials are E°(Cu²⁺/Cu) = +0.34 V and E°(Ag⁺/Ag) = +0.80 V at 25 °C.

Question Parts

( a )

Write the cell notation for the described cell.

( b )

State the overall cell reaction and calculate the standard cell potential, E°cell.

( c )

Using the Nernst equation at 25 °C, calculate the cell potential when [Cu²⁺] = 0.10 M and [Ag⁺] = 0.010 M.

( d )

If the concentration of Cu²⁺ is increased to 1.0 M while [Ag⁺] remains 0.010 M, predict qualitatively how the cell potential changes and justify your answer.
