Cathode (reduction): 2 H2O(l) + 2e− → H2(g) + 2 OH-(aq)Anode (oxidation): 4 OH-(aq) → O2(g) + 2 H2O(l) + 4 e−Overall reaction: 2 H2O(l) → 2 H2(g) + O2(g)

What are the 2 gaseous elements formed when electric current passes through acidified water?

The two gaseous elements formed are hydrogen gas (H2) and oxygen gas (O2). The electrolysis of acidified water splits the water molecule (H2O) into its constituent elements, hydrogen and oxygen, through the process of electrolysis.


Why on electrolysis of zinc nitrate zinc is formed on cathode?

The cathode is so named because it provides available free electrons, to which any cation such as zinc is attracted. When a zinc ion accepts an electron, it becomes a zinc atom and usually remains attached to the cathode, which therefore becomes plated with zinc. Since metallic zinc is itself electrically conductive, the process can continue until the supply of zinc cations from the solution is exhausted, so long as sufficient electrical energy is supplied.


Why are bubbles formed by the electrodes in an electrophoresis procedure?

Bubbles formed by the electrodes in an electrophoresis procedure are typically due to electrolysis of water. When current passes through the electrodes, water molecules are split into oxygen gas at the anode and hydrogen gas at the cathode, resulting in the formation of bubbles.


What is the precipitate formed when water is electolysed?

The composition of the precipitate, depends upon the type of water(distilled or tap) and type of electrode(iron, copper, etc) you are using. It may be Copper hydroxide or Iron hydroxide, and many possible products.


What are the properties of cations?

Cations are positively charged ions that are formed when an atom loses electrons. They are smaller than their parent atoms due to the loss of electrons, and they are attracted to the cathode in electrolysis. Cations play a crucial role in various chemical reactions and in the functioning of biological systems.

When electricity is passed through acidified water bubbles are formed this is because water?

When electricity is passed through acidified water, bubbles are formed because the electricity causes the water molecules to split into hydrogen gas and oxygen gas through electrolysis. The hydrogen gas is formed at the cathode and the oxygen gas is formed at the anode, creating bubbles as they escape from the solution.

What is formed at the anode and the cathode during the electrolysis of sodium iodide?

If a solution of NaI is electrolyzed, iodine is formed at the anode and hydrogen gas at the cathode. In the instance if it is the molten liquid of NaI, it would emit sodium from the sodium at the cathode and iodine at the anode.


What would be formed at the cathode and the anode during the electrolysis of sodium hydroxide solution?

Hydrogen gas would evolve from the cathode and oxygen gas would evolve from the anode.


What is product formed after electrolysis at the positive and negative electrodes respectively?

The answer depends on what the electrolyte is!


What products are formed during the electrolysis of sodium chloride solution?

during the electrolysis of Sodium Chloride chhlorine gas is produced at the anode and hydrogen gas is produced at the cathose.


What valuable product are formed from the electrolysis of brine?

Chlorine gas and sodium hydroxide, which is why it's called the chlor-alkali process.

Hydrogen and oxygen


What are the products of the electrolysis of molten potassium chloride?

There is Na+ and Cl- ions in the solution. Therefore, assuming the electrodes are inert, sodium ions will be discharged as sodium metal on the cathode and Chloride ions will be discharged from the anode as chlorine gas


How electrons are removed from water to produce hydrogen ions and oxygen gas.?

Electrons are removed from water molecules during a process called electrolysis, where an electric current is passed through water. The electrons are transferred to the anode, while hydrogen ions (H+) are released at the cathode, forming hydrogen gas. Oxygen gas is formed at the anode as a byproduct of the electrolysis process.
