a) while studying chemical effects of electric current in copper sulphate solution, why do we need some dilute sulphuric acid in it.
Answers
Answer:
Electroplating is the hydrolytic plating of one metal onto another, typically to stop corrosion of the metal or for aesthetic reasons. In order to create a thin coherent metal coating on the electrode, the procedure reduces the number of dissolved metal cations.
Explanation:
This process is known as electroplating.
Sulphuric acid in its diluted form does not react with copper.
As a result, pouring diluted sulfuric acid across a copper plate will not cause a reaction.
However, effervescence is seen when concentrated sulfuric acid is poured upon a copper plate. The effervescence is caused due to the evolution of hydrogen gas.
Hence, we need dilute sulfuric acid in the chemical effects of electric current in copper sulfate solution because the electrodes become conducting in nature.
