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.
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.
Why you need to replace positive electrodes?
aho 3'alasa keda :P
Is it true or false that Noble gases are inert gases?
Noble gases are inert gases because of a completely filled valence shell,hence they need not to satisfy their valency.
Why electrolysis does not take place in distilled water?
You will need a electrolyte for it conduct electricity such as sodium chloride (table salt).

How many electrodes does an EEG need?
Approximately 16-20 electrodes
How many electrodes does an Electroencephalography need?
Approximately 16-20 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
The cost of making sodium hydroxide includes the cost of the raw materials used what other costs involved in making sodium hydroxide?
To make sodium hydroxide, you need to electrolyse the solution of sodium chloride. Electricity is needed for electrolysis and that will cost money. There will also be the cost of equipment such as electrodes. (Electrodes have to be replaced after a while). Lastly, there may also be the cost of labour. The men who make sodium hydroxide will need to get paid.

Is brineconcentrated salt water a solution?
Brine is a salt solution. It does not need to be concentrated in order to be brine.
Do brine shrimp need water?
Yes, they do.
Will a mandarin dragonet eat baby brine shrimp?
Baby brine are really too small for a mandarin, you will need to raise the brine shrimp up to a larger size.
How much acidity do brine shrimp need?
Brine shrimp do not need acidity, it will die in acidic water. It needs alkaline water though (PH around 8).
Would two magnesium electrodes make a good wet cell that produces a lot of voltage why or why not?
No, because they are the same conductor and do not make a "ramp" for the electrodes to move along. They need to be different in order to make the electrodes move.
When brine shrimp grow do you need to get a bigger tank?
yes.
