We're being asked to calculate the emf generated by the cell when [Al3+] = 4.5×10‒3 M and [I‒] = 0.15 M.
We're going to calculate for Ecell using the following steps:
Step 1: Write the two half-reactions and determine the anode and cathode.
Step 2: Write the overall reaction and determine the number of electrons transferred (n).
Step 3: Calculate Ecell using the Nernst equation.
Step 1: Write the two half-reactions and determine the anode and cathode.
The standard emf for the cell using the overall cell reaction below is +2.20 V:
The emf generated by the cell when
[Al3+] = 4.5 x 10-3 M and [I-] = 0.15 M is _____ V.
