Hey there!!
When electricity is passed through acidified water,it dissociates into hydronium and oxygen ions..The hydronium ion(H3O +) is a positively charged radical known as cation..so it is produced at the cathode..
On the other side,The oxygen ion is a negatively charged radical known as the anion..so it is produced at the anode...
And also..the volume of gas liberated at Cathode(Hydrogen) is twice that of the gas liberated at the Anode (Oxygen)..This is because In water(H2O),Hydrogen has two moles whereas oxygen has only 1 mole present in it..
Hope it helps you!!
