describe an experiment to show the chemical effects of current
Answers
Answer:
A chemical reaction takes place when an electric current passes through a conducting solution. You can easily observe the chemical effects in the form of bubbles or gases in the solution. The chemical effects of electric current are used in the working of electrochemical cells.
Explanation:
Answer:
Chemical effects of electric current
When it flows through a conducting solution it always produces some effect. Chemical reactions occur when an electric current passes through a conducting solution. As a result, gas bubbles could form on the electrodes, metal deposits can be detected on electrodes and it may possible that the color of the solution will change. The type of solution and electrodes are used will determine the reaction and its effects.
Lets consider an experiment to see if some fruits and vegetables can likewise conduct electricity. Cut the potato into two parts and inserted the two copper terminals or wires of a tester into one-half part of the potato. After half an hour, it is observed that a greenish-blue mark on the potato around one wire whereas there was no such spot around the other wire. It is always the wire attached to the positive terminal that has a greenish-blue spot around it.
