Why do you add little sulphuric acid to copper sulphate solution during electroplating?
Adding a small amount of sulfuric acid to the copper sulfate solution during electroplating helps improve the conductivity of the solution. This allows for more efficient deposition of copper onto the object being plated. The sulfuric acid also helps to maintain the proper pH level of the solution, which is important for achieving a quality plating finish.
What else can I help you with?
Why should copper sulphate solution be acidified during copper electroplating?
Acidifying the copper sulfate solution helps to increase the conductivity of the solution, facilitating the electroplating process. It also helps to prevent the precipitation of copper hydroxide, which could interfere with the plating process. Additionally, the acid helps to maintain a stable pH level during electroplating.
What do copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled?
Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.
What occurs when copper reacts with dilute sulphuric acid?
When copper reacts with dilute sulphuric acid, copper sulfate and hydrogen gas are produced. The copper sulfate formed will be a blue solution. This reaction is a redox reaction, where copper is oxidized and hydrogen is reduced.
Method for manufacturing copper sulphate?
There are various method for manufacturing copper sulphate commercially. it can be manufactured by the action of sulphuric acid on copper in the presence of air/O2. reacting copper with dilute sulphuric acid in the presence of strong oxidising agents like HNO3. By converting copper into copper oxide and dissolution of oxide into dilute sulphuric acid. once we get liquid copper sulphate solution from reaction then the normal operations are filtration , concentration, crystallisation, separation & drying of crystals
What salt is formed when copper reacts with sulphuric acid?
When copper reacts with sulphuric acid, copper sulfate is formed. This reaction involves the displacement of hydrogen in sulphuric acid by copper, resulting in the formation of copper sulfate and hydrogen gas.
What liquid would you use in the electroplating bath to coat zinc with copper?
copper sulphate solution
What chemical should be added to copper carbonate to make copper sulphate?
Sulphuric acid, because "sulphuric" is what gives copper sulphate it's name

What is mixed with copper oxide to make copper sulphate?
Sulphuric acid is mixed with copper oxide to make copper sulphate through a chemical reaction.
Where is copper sulphate used?
for electroplating or wood presevative
Why aqueous solution of copper sulphate is acidic in nature?
Solution of Copper(2) sulphate is acidic in nature. This is due to the fact that in solution, copper sulphate reacts with water to produce copper(2)hydroxide and sulphuric acid: CuSO4 + H2O ------> Cu(OH)2 + H2SO4 Copper hydroxide is a weak base whereas Sulphuric acid is a very strong acid. Due to presence of a strong acid (sulphuric acid) this solution is acidic in nature. :)
What do copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled?
Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.
What happens when copper oxide reacts with dilute sulphuric acid?
Copper Oxide reacts with Sulphuric acid to form Copper Sulphate and Water.
What occurs when copper reacts with dilute sulphuric acid?
When copper reacts with dilute sulphuric acid, copper sulfate and hydrogen gas are produced. The copper sulfate formed will be a blue solution. This reaction is a redox reaction, where copper is oxidized and hydrogen is reduced.
What is the name of the acid that makes copper sulphate?
Sulphuric acid
What is made when you mix sulphuric acid copper carbonate?
copper sulphate and carbon dioxide
