The overall reaction 2co3+(aq) + 2cl–(aq) → 2co2+(aq) + cl2(g) has the standard cell voltage e°cell = 0.46 v. given e° = 1.36 v for the reaction cl2(g) + 2e– → 2cl–(aq), calculate the standard reduction potential for the following the half reaction at 25°c: co3+ + e– → co2+

The standard reduction potential for reduction half reaction is 1.82 V

Explanation:

The given chemical reaction follows:

Oxidation half reaction:  

Reduction half reaction:  

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.

To calculate the of the reaction, we use the equation:

We are given:

Putting values in above equation, we get:

Hence, the standard reduction potential for reduction half reaction is 1.82 V

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
