My question is: how much elctrical energy is required to separate 1 liter of water into hydrogen & Oxygen at sea leavel? I would like to see the method (equations) explained.
Thank you,

The electrical energy needed for water electrolysis at sea level can be calculated using the formula E = V x I x t, where E is the energy in Joules (J), V is the voltage in Volts (V), I is the current in Amperes (A), and t is the time in seconds (s). This formula is based on the laws of conservation of energy and Faraday's law of electrolysis.
Voltage plays a crucial role in calculating the electrical energy needed for water electrolysis at sea level. It determines the amount of electrical potential energy that is available to drive the reaction. The higher the voltage, the more energy is available, and the faster the reaction will occur.
The current is a measure of the rate at which electrical charge is flowing. In water electrolysis, the higher the current, the faster the reaction will occur, and the more energy will be consumed. Therefore, the amount of current needed will depend on the desired rate of reaction and the available voltage.
Yes, the type of electrolyte used can affect the amount of electrical energy needed for water electrolysis at sea level. Different electrolytes have different ion concentrations and conductivities, which can impact the rate of reaction and, therefore, the amount of energy required.
Yes, the altitude of the location can impact the amount of electrical energy needed for water electrolysis. This is because the higher the altitude, the lower the air pressure, and therefore, the lower the partial pressure of oxygen in the air. This can affect the efficiency of the electrolysis process and may require more energy to achieve the same results compared to performing electrolysis at sea level.
