Electrolysis of brine requires inert electrodes, such as platinum or graphite, to prevent the electrodes from reacting with the products of the electrolysis. Using inert electrodes ensures that the reactions at the electrodes are solely due to the electrolysis of the brine solution and do not introduce impurities or alter the chemical composition of the products.
What else can I help you with?
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.
What conditions are required for the electrolysis of salt?
To electrolyze salt (sodium chloride, NaCl) successfully, you need to dissolve it in water to form an electrolyte solution. Additionally, you need two electrodes (usually made of inert materials like platinum or graphite) to carry the electric current through the solution. Lastly, you need a direct current (DC) power source to provide the necessary electrical energy for the electrolysis process to occur.
Why is it important to know how reactive a metal is when it is extracted using electrolysis?
It is important to know the reactivity of a metal when extracting it using electrolysis because more reactive metals require more energy to extract. This affects the cost and efficiency of the extraction process. Additionally, the reactivity of the metal determines the conditions, such as voltage and electrodes, that need to be used during electrolysis.
How do you use electrolysis to remove salt from food?
To remove salt from food using electrolysis, you would need to create a solution with the food immersed in it. Then, by passing an electric current through the solution, the salt ions will be attracted to the electrodes and removed from the food. This process can be time-consuming and may alter the taste and texture of the food.
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 does a substance need to be a solution or molten for electrolysis to work?
For electrolysis to occur, a substance must be in a solution or molten state because this allows the ions to move freely. In solid form, the ions are fixed in place within a crystal lattice and cannot migrate to the electrodes. When dissolved in a solvent or melted, the ionic bonds break, enabling the ions to conduct electricity and participate in the electrochemical reactions at the electrodes. This movement of ions is essential for the process of electrolysis to effectively separate and produce elements or compounds.

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
Is brineconcentrated salt water a solution?
Brine is a salt solution. It does not need to be concentrated in order to be brine.
Why can you get pure gold straight out of the ground but you need furnaces or electrolysis to get iron or aluminum?
Gold is typically found in its pure form in nature due to its inert nature and resistance to oxidation. In contrast, iron and aluminum are chemically reactive metals that form compounds with other elements, requiring extraction processes like smelting or electrolysis to isolate them from their respective ores.
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.
