What will be the products on cathode and anode during electrolysis of the solution of magnesium sulphate?
Cathode - Hydrogen Anode - Oxygen
What forms at the cathode during electrolysis of a metal compound?
reduction reaction.
Where does copper collect during electrolysis?
The cathode, where the +ions in solution accept electrons and become neutral metal atoms.
What happens at the negative electrode during the electrolysis of molten aluminium?
Al3+ + 3e- --> Al(metal)
What does common salt break into during electrolysis of its solution?
The products of the electrolysis are sodium hydroxide and chlorine.
An electrode at which aluminium is deposited during electrolysis of alumina?
Cathode
What will be the products on cathode and anode during electrolysis of the solution of magnesium sulphate?
Cathode - Hydrogen Anode - Oxygen
What forms at the cathode during electrolysis of a metal compound?
reduction reaction.
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 a cationic molecule?
A cationic molecule is a positively charged ion. It is attracted to the cathode, or the negative pole, during electrolysis.
Where does copper collect during electrolysis?
The cathode, where the +ions in solution accept electrons and become neutral metal atoms.
What would happen if you used an alternating current during electrolysis?
the cathode and anode keeps interchanging between each other
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.
Why does the blue colour remains blue during electrolysis of copper sulphate solution using copper electrodes?
During the electrolysis of Copper sulphate ,at the cathode ,copper and hydrogen both being positively charged migrate towards the cathode.While at the anode
What is the equation for cathodic reaction?
During electrolysis a cation moves towards cathode where it accepts the electrons and becomes reduced. M+ + e- ------> M
Can you separate hydrogen in the sodium chloride solution?
NaCl itself will not render any hydrogen, however you can separate hydrogen from the water through the process of electrolysis. During electrolysis of NaCl solution, hydrogen will be evolved at cathode.
What is meant by anode and cathode?
Anode is positive electrode which attracts the negative anions while cathode is the negative electrode which attracts the positive cations during electrolysis.
