What will happen when electrolysis of dilute sodium chloride solution using copper and zinc electrode?
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
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.
Why is gas obtained at the cathode double at the anode?
Hydrogen is produced at the anode at twice the rate of oxygen produced at the cathode, because of the ratio of hydrogen to oxygen that makes up water: 2 : 1.
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-
When electric current pass through water.Which gases r obtained as anode and which obtain as cathode?
Oxygen at positive anode and Hydrogen at negative cathode

What will be the products on cathode and anode during electrolysis of the solution of magnesium sulphate?
Cathode - Hydrogen Anode - Oxygen

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 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 are the products of the electrolysis of lead nitrate solution?
Pure lead on the cathode and oxygen at the anode.
What are the two gases used to produce electricity in fuel cells?
The two gases used to produce electricity in fuel cells are hydrogen (H2) as the fuel and oxygen (O2) as the oxidant. In a fuel cell, hydrogen is fed to the anode (negative electrode) and oxygen is supplied to the cathode (positive electrode), where they react to produce water, heat, and electricity through an electrochemical process called the oxidation-reduction reaction.
Do plant produce when they have no oxygen?
Yes, plants produce oxygen and need carbon dioxide and sunlight to produce food.
How is oxygen obtained industrially?
There are several ways to obtain oxygen, the most common is to use electrolysis with water where they charge a negative anode and a positive cathode in water to separate the hydrogen and oxygen, the oxygen will go to the negative anode and can be collected from there.
