AIM OF THE EXPERIMENTAIM OF THE EXPERIMENT

To prove thatTo prove that• Water is made up of one molecule of Water is made up of one molecule of

oxygen and two molecules of Hydrogen oxygen and two molecules of Hydrogen i.e. Hi.e. H22O .O .

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

EXPERIMENTEXPERIMENT

• Take a stand with ringTake a stand with ring• Put the Saline water Put the Saline water

bottle inverted in the bottle inverted in the standstand

• Fill water in the bottle.Fill water in the bottle.• Put some Soda-bi-Put some Soda-bi-

carb in water.carb in water.

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

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

• Take two test tubesTake two test tubes• Put them on the rods Put them on the rods

inverted by taking inverted by taking care that there is no care that there is no air in them.air in 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 , we When measured , we find the length of one find the length of one gas level is double gas level is double than the otherthan the other

• Again we pass the Again we pass the current and let the current and let the test tubes fully filled test tubes fully filled with gaswith 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 brought match stick is brought near, it burns with a near, it burns with a pop soundpop sound

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