Given, for Sn ⁴⁺ / Sn ²⁺ , standard reduction potential is 0.15 ~V and for Au ³⁺ / Au , standard reduction potential is 1.5 ~V . For the reaction, 3 Sn ²⁺+2 Au ³⁺ 3 Sn ⁴⁺+2 Au the value of E_ cell ^ is,
Options
- A+1.35
- B+2.55
- C-1.35
- D-2.55
Correct answer
A. +1.35
Step-by-step solution
aligned E_ cell ^ &=E_ cathode ^ -E_ anode ^ &=1.5-0.15=1.35 ~V aligned
