In MOLTEN zinc chloride, At the cathode: Zn2+ + 2e- --> Zn(s)
At the anode: 2Cl- --> Cl2(g) + 2e- In CONCENTRATED aqueous zinc chloride solution, At the cathode: 2H+ + 2e- --> H2(g)
At the anode: 2Cl- --> Cl2(g) + 2e- (Zinc is not formed as it's Enaught value is very negative. Chlorine is still formed though.)
In dilute (less than 5%) squeous zinc chloride solution, At the cathode: 2H+ + 2e- --> H2(g)

Which element could be formed at the anode when a molten salt is electrolysed?
When a molten salt is electrolyzed, the element that could be formed at the anode is typically a halogen, such as chlorine or fluorine, depending on the composition of the salt. During the electrolysis process, anions migrate to the anode, where they are oxidized, releasing their electrons and forming gases. For example, in the electrolysis of sodium chloride (NaCl), chlorine gas (Cl₂) is produced at the anode.
How can copper be separated from solution of copper compounds?
Usually in a school experiment, you put copper solution into glass. Then you add Positively and negatively charged sticks which are connected with each other and plugged into electricity, which makes pure copper form on the negatively charged stick.
How is electrolysis used to purify metals?
TRUE!
What is an anode slime?
An anode slime is a sediment which settles at the bottom of a copper electrorefining cell, which is rich in silver, gold, selenium and tellurium.
What happens at the anode and cathode in the electrolysis of brine?
In the electrolysis of brine (saltwater), at the anode, chloride ions (Cl⁻) are oxidized to form chlorine gas (Cl₂). At the cathode, water molecules are reduced to produce hydrogen gas (H₂) and hydroxide ions (OH⁻). This process results in the formation of chlorine gas at the anode and hydrogen gas at the cathode, with sodium hydroxide (NaOH) remaining in the solution.
What can be used to split copper chloride into copper and chlorine?
Electrolysis can be used to split copper chloride into copper and chlorine. By passing an electric current through a solution of copper chloride, the chloride ions (Cl-) will be attracted to the positive electrode (anode) where they undergo oxidation to form chlorine gas, while the copper ions (Cu2+) will be attracted to the negative electrode (cathode) where they are reduced to form solid copper.
During the separation of copper chloride what element is formed at the anode?
During the electrolysis of copper chloride, chlorine gas is formed at the anode. This is because chloride ions (Cl-) are attracted to the positive electrode (anode) and are oxidized to form chlorine gas.
What is copper chloride split into by electrolysis?
When copper chloride is split by electrolysis, it may form copper metal at the cathode and chlorine gas at the anode. The copper ions gain electrons and get deposited on the cathode, while chloride ions lose electrons, releasing chlorine gas at the anode.
What happens to a copper chloride solution when an electric current passes through it?
When an electric current passes through a copper chloride solution, the copper ions (Cu2+) move towards the cathode and get reduced to form solid copper metal. Meanwhile, the chloride ions (Cl-) move towards the anode and get oxidized to form chlorine gas. This process is a type of electrolysis where chemical reactions are driven by the electric current.
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.
What happens at the anode during purification of copper?
At the anode during purification of copper through electrolysis, copper atoms lose electrons to become copper ions (Cu2+), which then dissolve into the electrolyte solution. This process allows impurities to remain behind at the anode, resulting in the purification of copper.
How could a solution of copper chloride and water be separated into its starting substances?
The copper chloride solution can be separated into its starting substances by a process called electrolysis. During electrolysis, an electric current is passed through the solution, causing the copper ions to be reduced at the cathode to form copper metal, and the chloride ions to be oxidized at the anode to form chlorine gas and water. This results in the separation of copper and chloride ions.
What is the electrode at which chlorine is produced?
Chlorine gas is produced at the anode during the electrolysis of aqueous sodium chloride (brine) solution. At the anode, chloride ions are oxidized to form chlorine gas.
What is used as the anode in sodium chloride electrolysis?
For example titanium (electrolysis in water solution).
When electric current is passed through a strong solution of brine then what will happen?
When electric current is passed through a strong solution of brine (sodium chloride in water), electrolysis occurs. Chlorine gas is produced at the anode, sodium metal at the cathode, and sodium hydroxide remains in solution. This process is known as the chlor-alkali process.
Which element could be formed at the anode when a molten salt is electrolysed?
When a molten salt is electrolyzed, the element that could be formed at the anode is typically a halogen, such as chlorine or fluorine, depending on the composition of the salt. During the electrolysis process, anions migrate to the anode, where they are oxidized, releasing their electrons and forming gases. For example, in the electrolysis of sodium chloride (NaCl), chlorine gas (Cl₂) is produced at the anode.
Why does the blue colour remains blue during electrolysis of copper sulphate solution using copper electrodes?
During electrolysis of copper sulfate solution using copper electrodes, the blue color of the solution remains because copper ions from the copper sulfate solution plate onto the cathode, replacing the copper atoms in the electrode. This does not change the color of the solution as the copper ions remain in solution, maintaining the blue color.
