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 must compounds be moltern for electrolysis to work?
Compounds must be molten in electrolysis because the ions present in the compound need to be free to move and carry electric current. In the molten state, the compound breaks down into its constituent ions, which can then undergo the electrolysis process. In a solid state, the ions are not free to move and the compound cannot conduct electricity.
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.
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.
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.
Is a solution a liquid that dissolves another substance?
No a solution is a liquid that has another substance dissolved in it.Added:When a solute ('the other substance') is dissolved in a solvent (liquid), this will result in a solution.
Ionic substance conducts when molten but decomposes?
i don't know, that's what i need to work out. I also don't know, bloody homework It has 12 letters, starts with E and ends with S After several hours of reading through dictionaries, browsing web pages and unfolding our brains me and my team of expert researchers came to the conclusion that the term we where looking for is.... Electrolysis
Can the density of a solution be used to determinr how much substance is dissolved in it?
yes, you just need to know the volume
What is a type of mixture in which one substance is dissolved into another?
This would be called a homogeneous mixture or a solution
Two basic parts of a solution?
The solute and the solvent...you can tell them apart because thesolute is: in a solution a substance that is dissolved in a solvent andthe solvent is, in a solution the substance that dissolves a solute and makes up the largest percentage of a solution.
How to make a solution in chemistry?
To make a solution in chemistry, you need to dissolve a solute in a solvent. The solute is the substance that is being dissolved, and the solvent is the substance that does the dissolving. Simply mix the two substances together until the solute is evenly distributed in the solvent.
How do you make a molar solution?
To make a molar solution, you need to dissolve the appropriate amount of a substance in a specific volume of solvent to achieve a certain concentration measured in moles per liter. This involves calculating the molar mass of the substance and using the formula C n/V, where C is the concentration, n is the number of moles of the substance, and V is the volume of the solution.
What is meant by decomposition potential?
Decomposition potential refers to the tendency of a substance to break down into simpler components under certain conditions, such as during a chemical reaction or electrolysis. It is a measure of the energy required to initiate the decomposition process.
