What is the primary use of carbon and graphite electrodes?
electrodes are used in all types of electric furnaces.
How is carbon used in chemistry?
Carbon applications:- as diamond to cut glass and for polishing- as graphite for electrodes, crucibles, etc.- as pencil mine- as carbon black
What are inert and active electrodes?
Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.
Which anode in electrolysis?
the anode (positive electrode) is the object that is going to be anodized. The cathode normally used is carbon rod that is inert.
How does electrolysis work?
Two electrodes must be connected to a battery and then placed in the compound to be electrolysed ( it must be in its molten form or dissolved in a solution). The battery is then switched on and an electric current passes through the compound, electrolysing it.
What alkaline solution is formed after the electrolysis of sodium chloride?
Sodium hydroxide, if the electrodes are inert to electro-dissolution, as are the carbon cathodes are usually used in large-scale electrolysis of this type.
Why isn't iron used as the electrodes in electrolysis?
Iron oxidizes too easily to be used in electrolysis.
What is the primary use of carbon and graphite electrodes?

Why are carbon rods used in some batteries?

Can you use water as a fuel in automobiles?
they didn't contain carbon and the by product of burning are carbon dioxide and water but can be used by electrolysis of water
Who invnted the telegraph?
In 1809, telegraph was invented Samuel Soemmering. He used 35 wires with gold electrodes in water and the message was read by the amount of gas caused by electrolysis.
Why do you think it is advantageous to use inert electrodes in the electrolysis processes?
If the electrodes are not inert, then they are going to become part of the chemical reaction, rather than just being conduits for electricity, and if they become part of the chemical reaction, they are going to get used up, and you will wind up with no electrodes.
Why are substances like platinum and palladium often used for carrying out electrolysis of aqueous solutions?
that is because platinum and palladium are inert elements and they wont react with the substance deposited on the electrode.. unlike if we use carbon electrodes, carbon will react with oygen deposited on it and escape out as CO2 gas
What are two important factors which control the process of electrolysis?
well two factors that affects electrolytic processes are, Quantity of electric current passed through the electrolyte and the nature of electrodes being used.
What can electrolysis be used to do?
Electrolysis can be used to decompose chemical compounds.
