Problem: When an aqueous solution of NaI is electrolyzed, what forms at the electrodes?a. Cathode: H2; anode: I2b. Cathode: Na; anode: I2c. Cathode: I2; anode: H2d. Cathode: Na; anode: H2e. Cathode: Br2; anode: Na

FREE Expert Solution

We're being asked to determine the products formed in the electrodes upon the formation of NaI.

In this case, we need to determine what reactions are in the cathode and anode

We can determine the anode and cathode by comparing their E° values.
