Oxygen production during electrolysis may be lower than expected due to factors such as inefficient electrolyte composition or concentration, inadequate electrode material or size, or improper current flow. It is important to ensure that all conditions are optimized for efficient electrolysis process to achieve expected oxygen yield.

What are the key differences between alkaline and PEM electrolysis in terms of efficiency and cost-effectiveness?
Alkaline electrolysis is more cost-effective but less efficient than PEM electrolysis. Alkaline electrolysis has lower efficiency due to higher energy consumption, while PEM electrolysis is more efficient but comes at a higher cost.
Why is aluminium extracted using the blast furnace and not electrolysis?
Aluminium is extracted using electrolysis because it has a high melting point, making it more energy efficient to use electrolysis rather than the blast furnace. The electrolysis process involves passing an electric current through a molten aluminum oxide mixture, which separates the aluminum from the oxygen.
What is electrolysis used to make?
Electrolysis is commonly used to produce pure elements from their compounds. It is used in various industrial processes to extract metals like aluminum, copper, and sodium from their ores. Additionally, electrolysis is used in the production of hydrogen and chlorine gas.
Hematite is composed of oxygen and what element that is less abuyndant than aluminum but more abundant than calcium?
Hematite is composed of oxygen and iron, which is less abundant than aluminum but more abundant than calcium in Earth's crust.
Why electrolysis of concentrated aqueous sodium chloride liberate chlorine rather than oxygen at the anode?
During electrolysis of concentrated aqueous sodium chloride, chloride ions are preferentially oxidized over water molecules at the anode due to their higher standard electrode potential. This results in the liberation of chlorine gas instead of oxygen gas.
Do 6 billion grains take up more or less space than you expected?
Less space than I expected.
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)
An oxygen deficient atmosphere has an oxygen concentration less than?
An oxygen deficient atmosphere has an oxygen concentration less than the normal level of around 21%.
What are the key differences between alkaline and PEM electrolysis in terms of efficiency and cost-effectiveness?
Alkaline electrolysis is more cost-effective but less efficient than PEM electrolysis. Alkaline electrolysis has lower efficiency due to higher energy consumption, while PEM electrolysis is more efficient but comes at a higher cost.
What is under frequency?
When the frequency is less than expected.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
Why is aluminium extracted using the blast furnace and not electrolysis?
Aluminium is extracted using electrolysis because it has a high melting point, making it more energy efficient to use electrolysis rather than the blast furnace.

Would you expect the second electron gain enthalpy of O as positive more negative or less negative than the first Justify your answer?
The second electron gain of an oxygen atom would be expected to be less negative. The reason for this outcome is that the oxygen atom gaining a second electron already has one electron and thus a negative charge. This negative charge repels the second electron to some extent, making the enthalpy of this process less negative than when the first electron was added to the neutral oxygen atom.
If your self employment income is less than expected do you pay less estimated taxes?
Yes
Was y2k for real?
There were some real problems, but less than expected.
Will the energy produced on combustion of hydrogen be more than the energy used for separation of hydrogen from water through electrolysis?
In theory, the energy produced by creating four oxygen-hydrogen bonds after breaking two Oxygen-oxygen and hydrogen-hydrogen bonds in the reaction O2 + 2H2 -> 2H2O (hydrogen combustion in oxygen) is exactly the same than the energy needed to break four oxygen-hydrogen bonds to create two oxygen-oxygen and hydrogen-hydrogen bonds in the reaction 2H2O -> O2 + 2H2 (water electrolysis) However, you will always have great energy loss during electrolysis (an important part of your energy will be used to warm up your water) and in getting back your energy from your oxygen and hydrogen gas (a combustible battery or a motor will warm up too).
Why does the voltage reading of 110 circuit is less than expected?
A load or a resistance
