The Na ions react to the anode, releasing the Cl- ions with enough energy to change into a gas. O B. The C- ions become oxidized at the cathode allowing them to form Clh molecules. O C. The Cl+ ions become reduced at the anode allowing them to form Clo molecules O D. The Na- ions react to the cathode, releasing the Cl-+ ions with enough energy to change into a gas. Previous Next

Explanation / Answer

NaCl spilt up into two ions Na+ and Cl-

anion goes to anode and cation goes to cathode

anode reaction ( oxidation) : 2 Cl-   ---------------> Cl2 + 2e-

cathode reaction (reduction) : Na+ + e -----------------> Na

so

correct answer is B
