What happens when salt and water were combined?
When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
When you dissolve salt into water what is the salt called?
Ionic compounds such as sodium chloride, that dissolve in water and dissociate to form ions, are called electrolytes. Please Watch animation 10.3 on ionic solutions.
Why is it that the dissolved salt in the water formed into salt again?
Explain that as the water evaporates, water molecules go into the air. Only the water evaporates, leaving the sodium and chloride ions behind. The sodium and chloride ions attract each other and re- form salt crystals.
Is salt dissolving in water chemical or physical?
For example salt dissolving in water is usually considered to be a physical change, however the chemical species in salt solution (hydrated sodium and chlorine ions) are different from the species in solid salt.
Is wood rotting a chemical change?

What happens when salt is burned?
These electrons become excited when energy is added — for instance, when you set the salt on fire. As the salt burns, the extra energy is lost — as light. Basic table salt burns yellow. The flames coming off of copper are bluish-green.
Can salt put out fire?
Salt will smother the fire almost as well as covering it with a lid, while baking soda chemically extinguishes it. But you’ll need a lot of each–toss on handfuls with abandon until the flame subsides. Avoid using flour or baking powder, which can explode in the flames instead of snuffing them out.
Can you throw salt on a fire?
Do not throw flour, biscuit mix, or baking powder onto the flames, as all these substances are combustible; only salt and baking soda are safe for extinguishing a fire. Do not throw salt or baking soda onto the flames from the side, which could cause the fire to leap out the back of the pan and catch elsewhere.
