Question

(1)Why is the volume of gas collected at one electrode double than the other
(2) What would happen if dilute H2SO4 is not added to water

Answer 1

because the formula of water is H2O which is 2 parts of hydrogen for 1 part of oxygen

if dil acid is not added the water won't conduct electricity

Answer 2

because in a water molecule hydrogen isin double amount as compared to oxygen that we know H2O if we don't add dilute H2 S o4 then action would take story because ion formation willform slowly
