Question

Activity 1.7
Anode
Take a plastic mug. Drill two holes at its
Oxygen
base and it rubber stoppers in these holes,
Insert carbon electrodes in these rubber
stoppers as shown in Fig. 1.6.
Test tube
Connect these electrodes to a 6 volt
battery
Graphite rod
Fill the mug with water such that the
electrodes are immersed. Add a few drops
of dilute sulphuric acid to the water,
Take two test tubes filled with water and
Invert them over the two carbon electrodes,
Switch on the current and leave the
Switch
apparatus undisturbed for some time.
You will observe the formation of bubbles
at both the electrodes. These bubbles displace water in the
test tubes.
Is the volume of the gas collected the same in both the test tubes?
Once the test tubes are filled with the respective gases, remove
them carefully
Test these gases one by one by bringing a burning candle close
to the mouth of the test tubes.
CAUTION: This step must be performed carefully by the teacher.
- What happens in each case?
Which gas is present in each test tube?​

Answer 1

Answer:

hydrogen and oxygen gas produced

Explanation:

In the mug electrolysis take place in water breaks down in to components namely hydrogen and oxygen gas. Amount of oxygen is double than hydrogen.
