what is electrolysis? explain why,in the electrolysis, acidified water is used.
Answers
Answer:
Acidified water is used for two reasons. Firstly, the ions provided by the acid greatly increase the electrical conductivity of the water, and this allows the decomposition of water to occur at a much increased rate. Secondly, the acid provides H+ions, which react, forming hydrogen, at the cathode.
Explanation:
Definition:
• Electrolysis is a process in which free ions in the conducting solution are dissociated or decomposed into simpler substances when an electric current is passed through it.
OR
It is a chemical process in which electric current is passed through a compound in liquid state to separate its constituent elements.
in the electrolysis, acidified water is used:
• As the concentration of free ions in water is quite low and so the conduction of electricity carriers ions are needed.
• So to increase the concentration of ions which basically increases the conduction of water acidified water is used
