Question

why is the amount of gas collected in one of the test tube in electrolysis in water double of the amount collected in other. name this gas.

Answer 1

HEY GUYS HERE IS YOUR ANSWER

The name of gas is OXYGEN.

Because the molecular formula of water is H2O, SO it have two molecules of oxygen atom and one molecule of hydrogen atom as shown below, that's why it has double amount of gas in beaker containing oxygen.

H2O

H O
1 2
SO by this it form H2O and we can say that it contains 2 molecules of oxygen atom and one molecule of hydrogen atom .

Answer 2

The chemical reaction involved in the electrolysis of water is From the above reaction it is clear that the amount of hydrogen gas and the oxygen gas formed are always in the ratio of 2:1. Therefore the volume of gas collected in the first test tube isdouble the volume of the gas collectedin second test tube.
