Adding a salt to water we obtain a solution (a homogeneous mixture) not a new chemical compound.

Why does the water bubble up then stop then it starts again just by adding salt?

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.


What is the independent variable in this experiment does adding salt to water lower its freezing point?

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.


Why does salt water have to reach a lower colder temperature to freeze?

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.


What did the salt do to the water to make it freeze slower?

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.


How do you switch your pool from chlorine sanitation to salt?

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.


When salt is added to boiling water at 100 degrees Celsius will the water boil faster or slower?

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.


Is it necessary to wash tile with a specific product in an new salt pool?

No


When salt and water are mix.is this a new substance?

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.


When solutions of an acid and a base are reacted the products are a A new acid and a new base b A salt and water c A metal oxide and water d A nonmetal oxide and water?

b) A salt and water. When an acid and a base react, they form water and a salt as products.


Reaction when the anhydrous salt samples were treated with the liquid?

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.


Does salt and water have a chemical reaction when they come in contact?

No. Salt and water becomes a solution, not a new compound.


What determines if a reaction is physical or chemical?

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.)
