Answer:Why is sodium not formed?

Explanation:You might have expected sodium metal to be deposited at the negative electrode. However, sodium is too reactive for this to happen so hydrogen is given off instead. hydrogen ions H +(aq) (from the water) are discharged at the negative electrode as hydrogen gas, H 2(g). In the electrolysis of sodium chloride, the Na+ ions might be expected to form sodium at the negative electrode. Instwd hydrogen gas is produced.This is because sodium chloride solution also contain H+ ions from some of the water :H20 (I) > H+ (aq) +OH- aq.
