2. ELECTROLYSIS OF WATER

3. Prepared by STUDENTS OF CLASS VII-A & B PROJECT GUIDE BASUDEV MOHAPATRA With special guidance from Jharana Sarkar (Dist Coordinator, AIF)

4. AIM OF THE EXPERIMENT To prove that Water is made up of one molecule of oxygen and two molecules of Hydrogen i.e. H 2 O. Water is made up of one molecule of oxygen and two molecules of Hydrogen i.e. H 2 O. By Passing electric current through water, oxygen and Hydrogen can be separated By Passing electric current through water, oxygen and Hydrogen can be separated

5. Instruments Required i) One baseless broad mouthed saline water bottle ii) 2 no stainless steel rods or 2 aluminum wires. iii) Cork of the saline water bottle. iv) Soda – bi – crab.. v) Water. vii) Copper wire viii) 2 test tubes of equal size and shape. ix) Battery of 6 volts. x) Stand with ring.

6. EXPERIMENT EXPERIMENT Take a stand with ring Take a stand with ring Put the Saline water bottle inverted in the stand Put the Saline water bottle inverted in the stand

7. Fill water in the bottle. Fill water in the bottle. Put some Soda-bi- carb in water. Put some Soda-bi- carb in water.

8. Fix the steel rods as shown in the figure and connect them with the copper wire to the Battery. Fix the steel rods as shown in the figure and connect them with the copper wire to the Battery.

9. We observe some gas bubbles coming out. We observe some gas bubbles coming out.

10. Take two test tubes Take two test tubes Put them on the rods inverted by taking care that there is no air in them. Put them on the rods inverted by taking care that there is no air in them.

11. When the current is passed we observe that some gas is collected in the test tubes. When the current is passed we observe that some gas is collected in the test tubes. When measured, we find the length of one gas level is double than the other When measured, we find the length of one gas level is double than the other

12. Again we pass the current and let the test tubes fully filled with gas Again we pass the current and let the test tubes fully filled with gas

13. Take out the tube which is first filled Take out the tube which is first filled When a burning match stick is brought near, it burns with a pop sound When a burning match stick is brought near, it burns with a pop sound

14. WHEN WE BRING THE MATCH STICK NEAR THE SECOND test tube THE MATCHSTICK BURNS WITH MORE FORCE WHEN WE BRING THE MATCH STICK NEAR THE SECOND test tube THE MATCHSTICK BURNS WITH MORE FORCE

15. CONCLUSION Water is made up of 2 parts of hydrogen one part oxygen. Water is made up of 2 parts of hydrogen one part oxygen. WATER H 2 +O=H 2 O WATER H 2 +O=H 2 O
