Take 25ml of water in a beaker and pass electricity through it. Then add a little sulphuric acid to it. What happens when dilute H2SO4 is added?

Solution
When dilute H2SO4 is added to water, the water becomes a good electrolyte. Hence, electricity passes through it.
When a little dilute sulphuric acid is mixed with water, a large number of hydrogen ions is formed due to the dissociation of H2SO4 into H+ ions, which allows the electricity to pass through water.
