How do i write the cell notation for a galvanic cell consiting of an Al electrode place in a 1.0M Al(NO)3(aq) solution and a Ag electrode placed in a 1.0M AgNO3(aq) solution. Write the half-reactions and the net ionic equation for the cell. Calculate the standard cell potential.

Oxidation half reaction : Al(s) $\rightarrow$→ Al3+(aq) + 3e-
Reduction half reaction : Ag1+(aq)+ 1e-$\rightarrow$→ Ag(s)
The over all net ionic redox reaction would be
Al(s) + 3 Ag1+(aq) $\rightarrow$→ Al3+(aq)+3 Ag(s) Line notation : Al/Al3+//Ag1+/Ag
Eocell=Eo (ox) + Eo (red)= Eo (Al/Al3+) +Eo (Ag1+/Ag) = 1.66 + 0.8 = 2.46 V
