Why sulphuric acid is added to water during electrolysis?
Answers
Answer:A few drops of sulphuric acid are added into water before electrolysis. ... To increase the conductivity of water a few drops of sulphuric acid is added .Being a strong acid it can ionize completely to release H+ ions. These H+ ions are responsible for the conduction of electricity.
Explanation:
Hi there,
☆ Pure water can't conduct the electricity due to absence of free charges as ions in solutions , so we can't do electrolysis for pure water
☆ But by adding small amount of sulphuric acid , ions well be exist in free state so the electrolysis process occures
☆ Sulphuric acid consider as a catalyst
♤ The equations
☆ Anode :2H2O + SO4-2=> O2 + 4e + SO4-2 + 4H+
☆ Cathode: 4H+ + 4e => 2H2
☆ The total equation
2H2O => O2 + 2H2
