How electrolysis is used in industry?
Manufacturing processes In manufacturing, electrolysis can be used for: Electroplating, where a thin film of metal is deposited over a substrate material. Electroplating is used in many industries for either functional or decorative purposes, as in-vehicle bodies and nickel coins.
What happens in the electrolysis of copper chloride?
Reminders: Electrolysis (of copper chloride) is a way of splitting up (decomposition) of the compound (copper chloride) using electrical energy. The electricity must flow through electrodes dipped into the electrolyte to complete the electrical circuit with the battery.
Is copper chloride hazardous?
* Copper Chloride can affect you when breathed in. * Contact can severely irritate and burn the skin and eyes with possible eye damage. * Repeated exposure can cause thickening of the skin. * Breathing Copper Chloride can irritate the nose, throat and lungs causing coughing and wheezing.
What are the industrial applications of electrolysis can these applications be called green processes?
Application of electrolysis in industry: Extraction of metals. Purification of metals. Electroplating of metals.

What solution is used in electrolysis?
During electrolysis, hydrogen ions H+ (from the water) are discharged at the negative electrode as hydrogen gas, H2. Chloride ions Cl- are discharged at the positive electrode as chlorine gas, Cl2. Sodium ions Na+ and hydroxide ions OH- (from the water) stay behind. They form sodium hydroxide solution, NaOH.
What is cucl2 used for?
What is copper II chloride used for? Copper (II) chloride is used as a catalyst for organic and inorganic reactions, textile dyeing and printing mordant, glass and ceramic pigment, wood preservative, disinfectant, insecticide, fungicide, and herbicide, and as a catalyst for hydrogen chlorine processing.
What is the pH of copper chloride?
Ingestion Copper chloride is an oxidizing agent and causes corrosive damage to mucous membranes. Concentrated solutions are acidic; a 0.2 M aqueous solution has a pH of 3.6.
Which of the reactions occurs at anode when the electrolysis of CuCl2 solution is carried out using platinum electrodes?
Cu2++2e−→Cu(s)
What are the products of electrolysis of CuCl2 using platinum electrode?
Q. When an aqueous solution of CuCl2 is electrolysed using Pt inert electrodes, the reaction at cathode and anode respectively are
- 4H2O(l)+4e−⟶2H2(g)+4¯OH2(aq);2H2O(l)−4e−⟶O2(g)+4H+ 0%
- 2Cu2+(aq)+4e−⟶2Cu(s);2H2O(l)−4e−⟶O2(g)+4H+(aq) 50%
- Cu2+(aq)+2e−⟶Cu(s);2Cl−(aq)−2e−⟶Cl2(g) 50%
