Hydrogen is produced at the negative electrode during electrolysis because it is less reactive than sodium. Sodium ions are more likely to undergo reactions at the positive electrode because they are more reactive and readily lose electrons to form sodium metal. Hydrogen ions are less reactive and instead gain electrons at the negative electrode to form hydrogen gas.
What else can I help you with?
What will happen when electrolysis of dilute sodium chloride solution using copper and zinc electrode?
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
What gas was produced at the positive electrode?
At the positive electrode, oxygen gas was produced.
When the switch is closed which electrode will attract the sodium ion?
Negative electrode Cathode One on the right
What happens when sodium ions come in contact with the negative electrode in a cell used for electrolysis?
When sodium ions come in contact with the negative electrode in a cell used for electrolysis, they accept electrons and get reduced to form sodium metal. This process occurs as part of the overall electrolysis reaction, where positive ions are reduced at the negative electrode while negative ions are oxidized at the positive electrode.
What is produced when Sodium Chloride undergoes electrolysis?
When sodium chloride undergoes electrolysis, it decomposes into sodium metal and chlorine gas. Sodium ions are attracted to the negative electrode (cathode) where they gain electrons to form sodium metal. Chloride ions are attracted to the positive electrode (anode) where they lose electrons to form chlorine gas.

When electric current is passed through molten sodium chloride sodium is deposited on positive or negative electrode?
The metal plates out on the negative electrode, which provides the electrons needed to neutralize its positive ions.

What gas is produced when aluminum reacts with sodium hydroxide?
When aluminum reacts with sodium hydroxide, hydrogen gas is produced along with sodium aluminate as a byproduct.
When sodium hydride is electrolyzed hydrogen gas is liberated at which electrode?
The anode, unusually enough.
What gas is produced when sodium and sulphuric react?
When sodium metal reacts with sulfuric acid (H2SO4), hydrogen gas (H2) is produced in addition to sodium sulfate (Na2SO4) and water (H2O). Sodium displaces hydrogen from sulfuric acid to form hydrogen gas.
What is the name of the gas that is produced when sodium metal is added to cold water?
The gas produced when sodium metal is added to cold water is hydrogen gas.
What gas is produced by sodium?
After the violent reaction of sodium with water hydrogen is released.
How could you separate sodium from the chlorine in the liquid salt compound?
One method to separate sodium from chlorine in a liquid salt compound like sodium chloride (table salt) is through electrolysis. When an electric current is passed through the liquid salt, the sodium ions migrate to the negative electrode (cathode) and chlorine ions migrate to the positive electrode (anode), allowing them to be collected separately.
