Heating a salt solution is a physical change, not a chemical change. When a salt solution is heated, the water in the solution may evaporate, or the solution may become more concentrated, but the chemical composition of the salt (sodium chloride) remains unchanged. This process only alters the physical state or the concentration of the solution, without any new substances being formed.

Is dissolving Skittles in salt and water a chemical or physical change?
Dissolving Skittles in salt and water is a physical change. The Skittles are still the same chemical compounds, but they are now dispersed throughout the water-salt solution.
Is Heating a hydrous salt to obtain an anhydrous salt a chemical or physical change?
if you mean epsom salts (magnesium sulfate) then heating it will result in a decomposition reaction, where magnesium oxide (s) and sulfur trioxide (g) is formed. The decomposition reaction is therefore a chemical change.
Is mixing sodium chloride and water a chemical or physical change?
Mixing sodium chloride and water is a physical change. The chemical composition of the sodium chloride (NaCl) remains the same in the solution, the sodium chloride molecules are simply dispersed in the water. The change is reversible and does not involve a chemical reaction.
Is a salt getting formed a chemical change or physical change?
I think it is a chemical change Forming underground it is a chemical change Salt forming from a saline solution for example h20 + NaCl --delta-> h2 + O2 + NaCl (This is not a balanced solution) This is a physical change, since there is no change to the Sodium Chloride
Is salt a chemical or physical property?
Salt is a chemical compound. It has chemical and physical properties.
Is dissolving salt in water a physical or chemical change and why how could you verify your answer?
Dissolving salt in water is a physical change because it does not alter the chemical composition of either the salt or water molecules. This change can be verified by allowing the water to evaporate, which would leave behind the original salt crystals without any chemical changes occurring.
What kind of chemical compound do salt in water form?
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Is salt forming a physical chance or chemical change?
It is a chemical change because the sodium(Na) is a liquid that forms with a yellow gas, chlorine(Cl), which changes the physical state to a dickmuncher solid, but ultimately they reacted with each other chemically to form salt (NaCl). It does change the physical state, but it is more of a chemical reaction.
Is salt dissolving in water and leaving a white residue a physical or chemical change?
Salt dissolving in water is a chemical change, the white residue is left when the water gets saturated by the salt and the salt starts to come out of solution to gain equilibrium. The residue can also be left behind when boiling off the water.
Is salting highways a chemical or physical change?
Salting highways results in a physical change because the salt dissolves in water to form a solution. This process involves a change in phase without altering the chemical composition of the salt itself.
Salt water is an example of is it a mixture solution or a chemical reaction?
Salt water is an example of a mixture. It is a solution made up of salt dissolved in water, without undergoing a chemical reaction. The components of salt and water can be separated by physical means such as evaporation.
What causes a chemical change?
No, not always. For example, if you mix salt and water, no chemical change takes place. The salt dissolves in the water and a solution is formed, which is not a chemical change because the salt and water retain their individual chemical compositions.
