Question Question 2
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.
In Activity 1.7, electrolysis of water is carried out and the products obtained are hydrogen and oxygen. As water contains 2 parts of hydrogen element as compared to only 1 part of oxygen element, hence, the amount of hydrogen gas collected in one test tube is double of the amount of oxygen gas collected in the other test tube.
