Why does using sodium bicarbonate as electrolyte when performing electrolysis of water produce less than one half volume oxygen for every one volume of hydrogen produced?

Because the electrolysis of water reaction always produces twice as much hydrogen (by volume or by mole) as they do oxygen.
H2O(l) -> H2(g) + 1/2 O2(g)

Write the balanced equation for the electrolysis of water. What type of reaction is this?
water itself is not a good electrolyte its electrolysis is performed in presence of anacid usually sulphuric acid, on electrolysis water produces hydrogen and oxygen gas. 2H2O = 2H2 + O2
Why you add sodium hydroxide in water as an electrolyte in hydrogen generation?
An electrolyte is a substance that produces ions in water, which allows it to conduct electricity. Water is split apart to produce hydrogen using electricity. Sodium hydroxide, despite being caustic, is a good electrolyte because it will not produce unwanted by-products during electrolysis.
What materials are made in electrolysis?
This depends on what you are electrolyzing. Water, the most common electrolyte, (the material being electrolyzed) separates into Hydrogen molecules on the cathode and Oxygen molecules at the anode. These gasses will bubble up to the top of the electrolysis chamber where they can be collected.
How do you get hydrogen from water?
Electrolysis of water gives off Hydrogen at the cathode (-ve chrged terminal).
What is electrolysis of aqueous sodium chloride?
Sodium metal can be obtained by electrolysis from molten mixture of sodium chloride and calcium chloride in Down's cell. The metal can not be obtained by electrolysis from aqueous solution, because hydrogen will evolve instead.
How is hydrogen made?
Most hydrogen is produced by electrolysis of water.
Does carbonate and bicarbonate both have hydrogen?
NO, only the Bicarbonate contains Hydrogen (H.) A Carbonate is represented as (CO3)^-2, whereas A Bicarbonate is (HCO3)^-1
When an electric current passes through water takes place breaking down the compound into hydrogen and oxygen?
Electrolysis of pure water is very slow and not significant; adding an electrolyte (an ionic salt) the electrolysis is a large scale process.
Is hydrogen chloride a electrolyte or non electrolyte?
Yes, it is a electrolyte. Bez has a ability to relese the one electron.
What is a process of decomposition?
The process of decomposition of an electrolyte, by passing an electric current from an outside source through it, is known as electrolysis. For example, when an electric current is passed through acidified water, water is decomposed into hydrogen and oxygen.
What can you get from water?
Electrolysis of water produce hydrogen.
How to separate hydrogen in water?
By the electrolysis of water.
