When is electrolysis used for extraction?
for extraction of iron
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.
Which two metals would produce the highest voltage if used for electrodes?
ironi and iron
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.
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 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
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.
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.
When was the telegraph first used?
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.
Will an ion with a negative charge conduct electricity?
Yes, this is what is happening in the process known as electrolysis. Electrolysis may be used to separate water into oxygen and hydrogen, for instance. In this case, negatively charged oxygen atoms (ions) and positively charged hydrogen atoms carry charges which are neutralised at the electrodes which are connected to the source of electricity.
Why can't aluminium be extracted the same way as iron?
It's not that it cannot be extracted through electrolysis, but it is because electrolysis is a very expensive process, and hence is only used for very reactive metals.
