The standard potential for Tl³⁺(aq)+ 3e^- $\rightarrow$ Tl(s) is the sum of the standard potentials for the two half-reactions:Tl³⁺(aq) + 2e^- $\rightarrow$ Tl⁺(aq) (E° = 1.21 V)Tl⁺(aq) + e^- $\rightarrow$ Tl(s) (E° = -0.34 V)Therefore, the standard potential for Tl³⁺(aq)+ 3e^- $\rightarrow$ Tl(s) is:E° = E°(Tl³⁺/Tl⁺) + E°(Tl⁺/Tl) = 1.21 V + (-0.34 V) = 0.87 V
