Hydrogen gas is produced.
It was sodium Sulfate!
during the electrolysis of Sodium Chloride chhlorine gas is produced at the anode and hydrogen gas is produced at the cathose.
Sodium chloride.
Hydrogen gas.
Ammonia
Sodium hydroxide and hydrogen gas are produced in a very vigorous reaction which can even cause fire
Hyrodgen / H2
Sodium metal is very reactive and would explode when in contact with water and produce hydrogen gas.
Hydrogen, H2
