Question

Why is the amount of gas collected in one
of the test tubes double of the amount collected in the other in electrolysis of water experiment name the gas​

Answer 1

The gas collected is HYDROGEN .Because hydrogen is denser than oxygen as it contain (H2O)

i.e two molecules of hydrogen.

Answer 2

Answer:

BTS

please mark me as brainliest

In Activity 1.7, water is electrolysed to give H2 gas at one electrode and O2 gas at the other electrode.

2H2O(l) → 2H2(g) + O2(g)

Thus two molecules of water on electrolysis give two molecules of hydrogen gas and one molecule of oxygen gas or in other words the amount of hydrogen gas collected would be double than that of oxygen gas.
