Why sulfuric acid added to water during electrolysis?
Sulfuric acid is added to water during electrolysis to increase the conductivity of the solution. This helps ions move freely in the solution and facilitates the electrolysis process by allowing the flow of electric current. It also helps in stabilizing the pH of the solution.
Why does the test tube turn yellow in electrolysis water experiment?
The yellow color in the test tube during an electrolysis water experiment is typically due to the presence of bromine or iodine. These elements can be released during the electrolysis process when the electrodes are made of certain materials that react with the electrolyte solution, such as potassium bromide or potassium iodide.
How are carbon electrodes utilized in the electrolysis of water process?
Carbon electrodes are used in the electrolysis of water process to conduct electricity and facilitate the separation of water into hydrogen and oxygen gases. The electrodes serve as the site for the redox reactions that occur during electrolysis, allowing for the production of hydrogen gas at the cathode and oxygen gas at the anode.
Why few drops of sulfuric acid are added to the water to carry out electrolysis of water?
Sulfuric acid is added to water for electrolysis to provide ions that increase the conductivity of water, making the electrolysis process more efficient. The presence of ions allows the electric current to flow more easily through the water, enhancing the splitting of water molecules into hydrogen and oxygen gases. Additionally, sulfuric acid helps to stabilize the pH of the water and prevent the formation of unwanted byproducts during the electrolysis process.
What role does an electrolysis catalyst play in the process of converting water into hydrogen and oxygen?
An electrolysis catalyst helps to speed up the chemical reaction that breaks down water into hydrogen and oxygen during the electrolysis process. It lowers the energy input needed for the reaction to occur, making the process more efficient.
Which component is reduced during the electrolysis of brine?
water
What is the name of the apparatus used to electrolysis of water?
The apparatus used for electrolysis of water is called an electrolysis cell or electrolytic cell. It typically consists of two electrodes connected to a power source, a container of water containing an electrolyte, and a mechanism to collect the gases produced during electrolysis.
Volume of gas are not equal during electrolysis of water?
During electrolysis of water, the volume of gas produced at the anode (oxygen) is twice that of the volume of gas produced at the cathode (hydrogen). This is because water molecules (H2O) split into two hydrogen atoms for every one oxygen atom when an electric current is passed through the water during electrolysis.
Why sulfuric acid added to water during electrolysis?
Sulfuric acid is added to water during electrolysis to increase the conductivity of the solution. This helps ions move freely in the solution and facilitates the electrolysis process by allowing the flow of electric current. It also helps in stabilizing the pH of the solution.

The yellow color in the test tube during an electrolysis water experiment is typically due to the presence of bromine or iodine. These elements can be released during the electrolysis process when the electrodes are made of certain materials that react with the electrolyte solution, such as potassium bromide or potassium iodide.
Is it harmful to drink water that has been in the electrolysis of water?
Drinking water produced through electrolysis is generally safe, as it is filtered and treated during the process. However, it's important to ensure the electrolysis equipment is properly maintained and the water source is clean to prevent any potential contamination.
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
What does salt do in the electrolysis of water?
Salt helps to increase the conductivity of the water, allowing for a more efficient flow of electricity during the electrolysis process. This results in the production of hydrogen and oxygen gases at the electrodes.
How are carbon electrodes utilized in the electrolysis of water process?
Carbon electrodes are used in the electrolysis of water process to conduct electricity and facilitate the separation of water into hydrogen and oxygen gases. The electrodes serve as the site for the redox reactions that occur during electrolysis, allowing for the production of hydrogen gas at the cathode and oxygen gas at the anode.
What will happen to water molecule when electricity is passed through water during electrolysis?
During electrolysis of water, the water molecule will be split into its constituent elements: hydrogen and oxygen gas. This is due to the electrical current breaking the bonds between the hydrogen and oxygen atoms in the water molecule, resulting in the release of hydrogen gas at the cathode and oxygen gas at the anode.
Why is potassium chloride used in electrolysis?
Potassium chloride is used in electrolysis because it can conduct electricity when dissolved in water. During electrolysis, the potassium ions and chloride ions in the solution allow for the flow of current, which leads to the movement of ions and the chemical reactions that occur at the electrodes. This allows for the production of desired products in electrolysis processes.
What elements are being decomposed in the water during electrolysis?
None are. The elements are not decomposed: the water is. The elements released by the reaction are hydrogen and oxygen.
