Question

Why is the amount of gas collected in one of the test tubes in Activity
1.7 double of the amount collected in the other ?Name this gas​

Answer 1

electricity is passed through water to decompose it. The amount of gas collected in cathode is twice that of at anode. The gas collected at cathode is hydrogen while the gas collected at anode is oxygen. Since the hydrogen and oxygen combine in the ration 2: 1 to form a water molecule, the amount of hydrogen gas is double that of oxygenAnswer:

Answer 2

Answer:

The gas evolved from the test tube are OXYGEN and HYDROGEN

Explanation:

Hydrogen gas is evolved at the anode which is more than the gas(oxygen) evolved at the cathode.The reason behind this HYDROGEN and OXYGEN always combine in the RATIO 2:1.

Hope this answer clear your doubt.
