What is the name of a process by which water is broken down into hydrogen and oxygen?
It's an example of electrolysis. Not unwanted hair removal, but that does use the same process. Electrolysis is the process of breaking down compounds by running an electric current through them.
Why the passage of electric current through a metallic conductor is not called electrolysis?
Because that's not what electrolysis is about. From Wikipedia: "...The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit..." When electrons just pass through a metal, no atoms or ions are exchanged - only the electrons.
What is electrolytic decomposition reaction?
a chemical decomposition reaction produced by passing an electric current through a solution containing ions is known as electrolytic decomposition reaction
What is brine electrolysis?
Brine elctrolysis is where a solution of sodium chloride (common table salt) dissolved in water is broken down into chlorine gas, hydrogen gas, hydroxide ions and sodium ions by passing and elctrical curren through the solution. The chlorine gas will liberate at the cathode and hydogen at the anode, and the two ions produced will combine to form a solution of sodium hydroxide, a very strong alkali which has many applications. (The NaOH solution will be, when the reaction is complete, in place of the NaCl solution). Hope this is useful!!
Ions that are made of more than one atom are examples of what?
Ions made up of more than one atom are called polyatomic ions.
What the factors that affect the preferential discharge of ions at the anode and the cathode?
how am i suposed to answer it if i am asking wat it is
Where does anions and cations come into electrolysis?
Anions are negatively charged ions that move to the anode during electrolysis, where they give up electrons. Cations are positively charged ions that move to the cathode during electrolysis, where they gain electrons. This movement and exchange of ions is essential for the transfer of charge and the chemical reactions that occur during electrolysis.
Why does the color of copper sulfate solution changes during electrolysis?
The color change in copper sulfate solution during electrolysis occurs because copper ions from the solution are attracted to the cathode, where they are reduced to form solid copper metal. This causes the solution to turn from blue to clear as the copper ions are removed.
Why chloride ions are discharged at anode instead of hydroxide ions during the electrolysis of brine?
Chloride ions have a lower standard reduction potential than water, making them easier to oxidize at the anode compared to hydroxide ions. Therefore, chloride ions are preferentially discharged at the anode during the electrolysis of brine.
Why does the concentration of tin sulphate solution not change during the electrolysis?
The concentration of tin sulphate solution does not change during electrolysis because the tin ions are deposited onto the cathode to form solid tin metal, while the sulfate ions remain in the solution. This maintains a constant concentration of tin ions in solution.
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.
Which type of elements form at the anode?
At the anode, positive ions are typically formed or attracted towards it during electrolysis. These positive ions are usually cations, which are ions with a positive charge. The anode itself typically undergoes oxidation during the process.
An electrode at which aluminium is deposited during electrolysis of alumina?
Cathode is the electrode at which aluminium is deposited during electrolysis of alumina. Aluminum ions (Al3+) are reduced to form solid aluminum metal at the cathode.
How is sodium sulfate involved in the process of electrolysis?
Sodium sulfate is used as an electrolyte in the process of electrolysis. It helps conduct electricity and allows ions to move between the electrodes, facilitating the separation of elements during the electrolysis process.
How does the anode lose mass during the process of electrolysis?
During electrolysis, the anode loses mass because it releases electrons, which causes the metal ions in the anode to turn into metal atoms and dissolve into the electrolyte solution.
Can Na be extracted from the electrolysis of its aqueous solution of Na-Cl?
Yes, sodium (Na) can be extracted from the electrolysis of its aqueous solution of sodium chloride (NaCl). During electrolysis, sodium ions are reduced at the cathode to form elemental sodium. Meanwhile, chloride ions are oxidized at the anode to produce chlorine gas.
Where does copper collect during electrolysis?
The cathode, where the +ions in solution accept electrons and become neutral metal atoms.
