Question 28

Multiple Choice

What is the Ecell for the following cell at 25 °C?
Pt(s) ∣ Sn2+ (aq,0.233 M) ,Sn4+ (aq,1.05 M) What is the E<sub>cell</sub> for the following cell at 25 °C? Pt(s) ∣ Sn<sup>2+</sup> (aq,0.233 M) ,Sn<sup>4+</sup> (aq,1.05 M)    Ag<sup>+</sup> (aq,2.22 × 10<sup>-2</sup> M) ∣ Ag(s)  Ag<sup>+</sup>(aq) + e<sup>-</sup> → Ag(s) E° = 0.800 V Sn<sup>4+</sup>(aq) + 2 e<sup>-</sup> → Sn<sup>2+</sup>(aq) E° = 0.154 V A) 0.763 V B) 0.529 V C) 0.412 V D) 0.680 V E) 0.578 V Ag+ (aq,2.22 × 10-2 M) ∣ Ag(s)
Ag+(aq) + e- → Ag(s) E° = 0.800 V
Sn4+(aq) + 2 e- → Sn2+(aq) E° = 0.154 V
