How many electrons would be required to deposit 6.35grams of copper at cathode during the electrolysis of an aqueous solution of copper sulphate?
To determine the number of electrons required to deposit 6.35 grams of copper, you need to first calculate the moles of copper deposited using the molar mass of copper. Then, use Faraday's constant (1 mol of electrons = 1 Faraday) to convert moles of copper to the number of electrons. Finally, multiply the number of moles of electrons by Avogadro's number to get the total number of electrons required.

Why sulfuric acid added to water during electrolysis?
Sulfuric acid is added to water during electrolysis to increase the conductivity of the solution. This helps ions move freely in the solution and facilitates the electrolysis process by allowing the flow of electric current. It also helps in stabilizing the pH of the solution.
How is silver electrolysis done?
In silver electrolysis, a silver anode is immersed in a solution containing a silver salt. When an electric current is passed through the system, silver ions from the anode move to the cathode, where they gain electrons and deposit as solid silver. This process allows for the purification and extraction of silver from its ore.
After electrolysis of brine solution what is the pH of that solution?
The pH of the solution after electrolysis of a brine solution will depend on the concentration of the resulting ions in the solution. The electrolysis of brine solution produces chlorine gas, hydrogen gas, and sodium hydroxide. The pH of the solution will increase due to the formation of sodium hydroxide, making it alkaline.
Can you separate hydrogen in the sodium chloride solution?
No, you cannot separate hydrogen from a sodium chloride solution by electrolysis because sodium chloride does not contain hydrogen in a form that can be readily separated through electrolysis. Sodium chloride solution will only undergo electrolysis to produce chlorine gas at the anode and sodium metal at the cathode.
Why do not covalent compounds undergo electrolysis?
Covalent compounds do not undergo electrolysis because they do not dissociate into ions in solution to conduct electricity. In order for electrolysis to occur, there needs to be free-moving ions in the solution to carry the current. Covalent compounds remain as intact molecules with strong bonding, so they do not produce the necessary ions for electrolysis.
Where does copper collect during electrolysis?
The cathode, where the +ions in solution accept electrons and become neutral metal atoms.
Are there dangerous byproducts from electrolysis on a solution of calcium chloride and water?
Electrolysis of calcium chloride solution release chlorine.
Why does electrolysis involves redox reactions?
Electrolysis involves redox reactions because it requires the transfer of electrons between the electrodes and the electrolyte solution. The anode undergoes oxidation (loses electrons) while the cathode undergoes reduction (gains electrons), which is the basis of redox reactions. This electron transfer allows for the decomposition of the electrolyte into its constituent elements.
What is the electrolysis of sodium chloride?
1. The products of the molten sodium chloride electrolysis are sodium and chlorine. 2. The products of the water solution of sodium chloride electrolysis are sodium hydroxide and hydrogen.
What is used as the anode in sodium chloride electrolysis?
For example titanium (electrolysis in water solution).
What does common salt break into during electrolysis of its solution?
The products of the electrolysis are sodium hydroxide and chlorine.
What chemicals can be obtained from the electrolysis of sodium chloride?
Electrolysis of a water solution: sodium hydroxide, hydrogen, chlorine..Electrolysis of molten NaCl: sodium, chlorine.

Explain why a substance needs to be either in a solution or molten for electrolysis to work?
Because electrolysis needs a liquid to conduct the electricity.
