CHEGG You are titrating 25.025.0 mL of 0.0100 M Sn2 Sn2 in 1 M HCl HCl with 0.0500 M Tl3 Tl3 resulting in the formation of Sn4 Sn4 and Tl Tl . A PtPt indicator electrode and a saturated Ag|AgCl Ag|AgCl reference electrode are used to monitor the titration. What is the balanced titration reaction

Tl³⁺ + Sn²⁺ → Tl⁺ + Sn⁴⁺

Explanation:

In a redox reaction, one compound is oxidized (Loosing electrons) whereas the other compound is reduced (Gaining electrons). In the reaction, the half-reactions of oxidation and reduction are:

Sn²⁺ → 2e⁻ + Sn⁴⁺ (Oxidation: Loosing electrons)

Tl³⁺ + 2e⁻ → Tl⁺ (Reduction: Gaining electrons)

The sum of both reactions gives:

Tl³⁺ + Sn²⁺ + 2e⁻ → Tl⁺ + 2e⁻ + Sn⁴⁺

Subtracting the electrons:
