Question

Which one of the following liberates oxygen immediately when passed into water

Answer 1

Answer:

Electric Current

Explanation:

As we know that when we pass an electric current in the water, oxygen gas liberates at the electrode which is known as anode. As we know that anode is connected to the positive terminal of a battery or cell. According to the electromagnetic theory, like charge repel each other whereas, unlike or opposite charge attract each other. So that, the positive charged electrode (Anode) always attract the negative charge particles called oxygen gas.
