AIM OF THE EXPERIMENTAIM OF THE EXPERIMENT

To prove thatTo prove that

• Water is made up of one molecule Water is made up of one molecule of oxygen and two molecules of of oxygen and two molecules of Hydrogen i.e. HHydrogen i.e. H22O .O .

• By Passing electric current through By Passing electric current through water, oxygen and Hydrogen can water, oxygen and Hydrogen can be separated be separated

EXPERIMENTEXPERIMENTEXPERIMENTEXPERIMENT

• Take a stand with Take a stand with ringring

• Put the Saline Put the Saline water bottle water bottle inverted in the inverted in the standstand

• Fill water in the Fill water in the bottle.bottle.

• Put some Soda-bi-Put some Soda-bi-carb in water.carb in water.

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

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

• Take two test Take two test tubestubes

• Put them on the Put them on the rods inverted by rods inverted by taking care that taking care that there is no air in there is no air in them.them.

• When the current is When the current is passed we observe passed we observe that some gas is that some gas is collected in the test collected in the test tubes.tubes.

• When measured , When measured , we find the length we find the length of one gas level is of one gas level is double than the double than the otherother

• Again we pass the Again we pass the current and let the current and let the test tubes fully test tubes fully filled with gasfilled with gas

• Take out the tube Take out the tube which is first filledwhich is first filled

• When a burning When a burning match stick is match stick is brought near, it brought near, it burns with a pop burns with a pop soundsound

• WHEN WE BRING WHEN WE BRING THE MATCH STICK THE MATCH STICK NEAR THE SECOND NEAR THE SECOND test tube THE test tube THE MATCHSTICK MATCHSTICK BURNS WITH MORE BURNS WITH MORE FORCEFORCE

CONCLUSION CONCLUSION

• Water is made up of 2 parts of Water is made up of 2 parts of hydrogen one part oxygen .hydrogen one part oxygen .

WATER WATER HH22++OO=H=H22OO
