Why do we add little dilute sulphuric acid to copper sulphate solution during electroplating? *
Answers
Answer:
To increase the conductivity of the liquid
Explanation:
The sulfuric acid in a copper electrolyte is there for two reasons, one is to keep the copper in solution, you only used a 0,1 m solution, if you use higher concentrations your copper sulfate will partially get Cu(OH)2 . Also the sulfuric acid gives you a better conductivity and with this comes a better throwing power
Answer:
Reason of adding little dilute sulphuric acid to copper sulphate solution during electroplating :
To increase the conductivity of the solution
Electroplating involves the process of electrolysis. The way it works is that the solutions conduct electricity. During electroplating, we add a few drops of dilute sulfuric acid to the copper sulfate solution to increase the conductivity of the solution.
Add a few drops of sulfuric acid to a beaker of water and heat it. When the water starts to boil, add the copper sulfate powder and stir slowly. Continue to dissolve the solute until no more solute dissolves. Filter the solution and cool it down. After viewing, you can separate the copper sulfate crystals.
Sulfuric acid dissolves all traces of copper metal or its oxides as an impurity in the solution and also converts them into copper sulfate.
