consider the titration of 50 mL on 0.10M Sn2+ with 0.10M Tl3+

A) Wite the equation for the reaction that occurs between Sn2+ and Tl3+

[tex]Sn^2^++Tl^3^+\longrightarrow\ Sn^4^++Tl^+[/tex]

Correct?

Thallium is most stable at 1+ oxidation state, and tin(II) ions are present to reduce it. Tin(IV) ions will be produced in this redox reaction, so your redox reaction is correct.

ok good.

what is the half cell potential after 5.00mL of Tl[tex]^3^+[/tex]?

[tex]E_1_/_2=0.139-\frac{0.05196}{2}log\frac{1}{4.5}[/tex]
[tex]E_1_/_2=0.156v[/tex]

this right also?

The formula is something like that, but I don't remember the logarithm ratio in which you wrote 4.5. However, it seems okay.
