Fe²⁺ + 2e^- $\rightarrow$ Fe(s) E° = -0 $\rightarrow$ H₂(g) E° = 0

question 16

Short Answer

Fe²⁺ + 2e^- $\rightarrow$ Fe(s) E° = -0.440 V
2H⁺ + 2e^- $\rightarrow$ H₂(g) E° = 0.000 V
In a galvanic cell, the iron compartment contains an iron electrode, and [Fe²⁺] = 1.00 *10^-3 M. The hydrogen compartment contains a platinum electrode (P_H2 = 1.00 atm) and a weak acid HA at an initial concentration of 1.00 M. If the observed cell potential is 0.333 V at 25°C, calculate K_a for the weak acid HA at 25°C.
