Adding a salt to water we obtain a solution (a homogeneous mixture) not a new chemical compound.
Adding salt to boiling water will actually make the water boil slower. Salt increases the boiling point of water by raising its boiling point temperature. As a result, it will take longer for the water to reach the new, higher boiling point temperature and thus boil.
Could be either or both. Depends on the method used to purify the water. If you use reverse osmosis or distillation, it would be physical. If the water is treated with chlorine, it would be chemical.
No, mixing salt with water does not create a new substance. The salt dissolves in the water but the chemical makeup of both substances remains the same. This is a physical change, not a chemical change.
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Water softener salt can be harmful to new concrete as it may promote efflorescence, which is the appearance of white, powdery substance on the surface of the concrete. It's best to avoid using water softener salt near new concrete to prevent potential damage.
When you add the salt it increases the boiling point of the water, so bubbling stops until this new solution reaches its boiling point. Adding salt, sugar, or any solute to water raises the boiling point and lowers the freezing point of water.
salt. added by new author: As the amount of salt in the water iw increased the freezing point of water is decreased i.e. lowered. This is a negative correlation.
This phenomenon is called freezing point depression. Adding a solute (salt) to a solvent (water) the vapour pressure of water decrease; a new equilibrium is obtained at a lower temperature than 0 oC.
Adding salt to water will lower the freezing point, thus requiring the salt water to get colder before it will freeze - it thus takes longer to freeze because it takes additional time to cool from the normal freezing point on down to the new (colder) freezing point.
You need a salt water chlorinator. This can be a add-on to your existing setup or a whole new combined unit. You then add salt to your pool (mine is 20,000 litres and takes 60kg of salt at start of season), and then the salt water chlorinator (which sits in-line with one of your water hoses) makes chlorine from the salt using a chemical/electrical reaction. Beats buying and adding chlorine by hand :-) Hope that helps.

No
When salt and water are mixed, it does not create a new substance. The salt dissolves in the water to form a homogeneous mixture known as a solution. The properties of salt and water remain the same even after they are mixed, as they can be separated by physical means such as evaporation.
b) A salt and water. When an acid and a base react, they form water and a salt as products.
Usually, when a salt anhydrate is treated with water, its crystalline structure will reappear. Many solids are crystalline when the water of hydration, or water of crystallization is present. If you vaporize this away with heat, the crystalline structure collapses and you are usually left with a powdery anhydrate. Add water and it re-crystallizes. Be careful though: adding the water back will also release the heat you put into it to remove it. So adding the water is an exothermic process.
No. Salt and water becomes a solution, not a new compound.
If you mix something and it actually mix forming a new compound either solid or fluid, then the reaction is chemical. this can be as easy as burning a sheet of paper. The reaction is chemical and triggered by heat. The product you get is compositionwise different to the original product. If having a glass of water and a glass of salt and you then mix the sand with the salt, then this would be a physical reaction. The salt and water mix, but does not actually form a new compound, only a mixture of the two. Another physical reaction is melting of ice (The water is still water even though it is a solid as in ice.)
