Aim: To study electrolysis of water. Activity: Take a plastic mug. Drill two holes at the base of the mug. Fix two rubber corks in it, as shown in the figure 1.6. Arrange the test tubes in inverted position such that carbon electrodes remains in it as shown in the figure. Add water in a mug such that electrodes are immersed. Add a few drops of dilute sulphuric acid to water. Connect electrodes to a 6 volt battery. Now, switch on the current and leave the apparatus undisturbed for some time. Which gas is evolved at cathode during electrolysis of water ?
