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.
What element is an inert metal often used in electrodes?
Platinum is an inert metal often used in electrodes due to its stability and resistance to corrosion. It is commonly used in medical devices, fuel cells, and laboratory equipment.
What is Pt electrodes?
Pt electrodes refer to electrodes that are made of platinum. These electrodes are commonly used in various electrochemical applications due to platinum's inert nature, high conductivity, and stability in corrosive environments. Pt electrodes are versatile and can be used in different setups such as in fuel cells, sensors, and electrophysiology experiments.
Why you use only platinum electrodes in conductometric titrations?
Platinum electrodes are commonly used in conductometric titrations because they are inert, meaning they do not react with the solutions being tested, ensuring accurate measurements. In addition, platinum electrodes have good electrical conductivity and stability, making them reliable for consistent and precise titration results.
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.
Why do electrolysis of brine need inert electrodes?
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 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 inert metal is often used in electrodes and has an atomic number of 78?
The inert metal often used in electrodes with an atomic number of 78 is gold (Au).
Why are the electrodes used in electrolytic processes such as in the Downs cell and in the Hall-Heroult process always made of inert substances such as graphite or platinum.?
because they are good conductors of electricity and do not react with the electrolytes

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.

What are the products of the electrolysis of molten potassium chloride?
There is Na+ and Cl- ions in the solution. Therefore, assuming the electrodes are inert, sodium ions will be discharged as sodium metal on the cathode and Chloride ions will be discharged from the anode as chlorine gas
