During the electrolysis of water, oxygen is produced at the anode because the anode is positively charged and attracts negatively charged hydroxide ions (OH-) from the water. At the anode, hydroxide ions are oxidized to release oxygen gas as a byproduct, while releasing electrons to complete the circuit.

Is anode a negative electrode of hydrogen - oxygen fuel cell?

No, the anode is the positive electrode in a hydrogen-oxygen fuel cell. At the anode, hydrogen gas is oxidized to produce protons and electrons. The electrons flow through an external circuit to the cathode, where they combine with oxygen and the protons to form water.


How could a sample of gas be collected at the anode during-electrolysis of copper sulfate?

A sample of gas collected at the anode during the electrolysis of copper sulfate would likely be oxygen gas (O2) due to the oxidation of water at the anode. This would be because during this process, water is split into oxygen gas and protons, with the oxygen gas being produced at the anode.


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.


Will using potassium hydroxide during electrolysis produce chlorine gas?

If you mean just potassium hydroxide or its aqueous solution, then no, because their are no chlorine atoms present. The only elements present are potassium, hydrogen and oxygen. Molten KOH produces potassium at the cathode and oxygen at the anode, and the solution gives hydrogen at the cathode and oxygen at the anode.


What electrode do brine and chlorine produce after electrolysis?

Chlorine is produced at the anode. Brine at the cathodeOxidation reaction: 2 Cl- --'anode'--> Cl2 + 2e-

What will be the products on cathode and anode during electrolysis of the solution of magnesium sulphate?

At the cathode, magnesium metal will be produced, while at the anode, oxygen gas will be produced. This is because during the electrolysis of magnesium sulfate, magnesium ions will be reduced at the cathode to form magnesium metal, and water molecules will be oxidized at the anode to form oxygen gas and hydrogen ions.


What are the products of H2O?

The products of the chemical reaction involving water (H2O) can vary depending on the conditions. In general, when water undergoes electrolysis, it can produce hydrogen gas (H2) at the cathode and oxygen gas (O2) 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.

How do dissolved oxygen meters work?

A dissolved oxygen meter measures the oxygen pressure in water. An anode is covered with water to halt the oxygen probe in the DO to give a reading.


What two gaseous elements are produced when an electric current passes through acidified water?

Hydrogen and oxygen both r produced hydrogen at cathode and oxygen at anode.

What are the products of the electrolysis of lead nitrate solution?

Pure lead on the cathode and oxygen at the anode.


When electric current pass through water.Which gases r obtained as anode and which obtain as cathode?

When an electric current passes through water, hydrogen gas is obtained at the cathode (negative electrode) and oxygen gas is obtained at the anode (positive electrode) through the process of electrolysis.
