The anode and cathode are defined by the flow of current.
- The cathode is the negatively charged electrode.
- The anode is the positively charged electrode.

The cathode ray is a stream of electrons.
Why sulpuric acid is used in battery?
In a battery, there is a cathode, that gives off electrons in a chemical reaction, and an annode, which absorbs electrons in a complimentary chemical reaction. A car battery uses lead (which I will call by its chemical symbol Pb) as the cathode, and lead oxide (PbO) as the annode, both of which are bathed in Sulphuric acid. Lead is oxidized by water in the reaction Pb + H2O = PbO + 2H+ + 2e- (the symbol H+ stands for a hydrogen ion, and e- stands for electrons). The reaction at the annode is PbO + 2H+ + 2e- = Pb + H2O This regenerates the lead, making the car battery rechargable. The Sulphuric acid is a source of H+ which is used to get the reaction going at the annode (the cathode reaction is also a source of H+, but the reaction at the annode requires a large amount of H+ to get going) so Sulphuric acid can be considered a catalyst for this reaction.
What do you mean about composition in chemistry?

Can you use cpvc pipes for underground gas piping?
Only if it is wraped pipe -- And prime and wrap fittings also and install a annode making sure your annode is lower than your pipe
What causes a bad odor to develop inside your water heater?
Most water heaters have what is called a "sacrafical annode." This is fitted to save the heater from "agressive" water, hence the use of the word sacrafical. The Annode is sacraficed to save the heating vessel. If there is even a tiny amount of hydrogen sulphide (H2s) present in the water, the annode rod will make the problem worse and heated water will smell like rotten eggs. Try removing the annode rod and I bet it will be the end of your problem. Please note that removing the rod may affect your warrenty. I would love to know if this helps, I am pretty sure it will.

How hydrogen and oxygen is separated from water?
That can with water, which is 2 parts hydrogen and 1 part oxygen. Perhaps one process can be with electrolysis. That's having two carbon rods in water, very strong DC voltage and current. Then oxygen bubbles at one rod, and hydrogen at the other.
What is common cathode?

What is the charge of the particle in cathode rays?
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
