Above diagram shows the experiment of electrolysis of acid mixed water.
Switched on the current and left the apparatus undisturbed for some time.
Formation of bubbles is observed at both the electrodes. These bubbles displace water in the
test tubes.
Once the test tubes are filled with respective gases, should be removed carefully.
With reference to the above information, answer the followings:
a) Is the volume of the gas collected the same in both the test tubes?
b) If these gases are tested one by one by bringing a burning candle close to the mouth of the
test tubes:
What happens in each case (mention each observation with name of the gas)?
c) Mention the type of the reaction.
Answer:
1) no
2)hydrogen explosively burns with a pop sound
but in oxygen the flame of candle grows bigger
3) electrolysis of water is eclectricaldecomposition reaction
