Salt dissolves in water. Here's a rather complicated explanation of why this happens: Salt is made when a sodium atom loses one electron, and the electron moves to a chloride atom. When this happens, the sodium atom becomes positively charged and the chloride atom becomes negatively charged. Positive and negative atoms attract each other, so the sodium and the chloride are attracted and form an ion called sodium chloride (otherwise known as salt). Water molecules are made of two hydrogen atoms and one oxygen atom. The electrons in the molecule tend to spend more time around the oxygen atom. This gives the oxygen atom in the molecule a slightly negative charge (and the hydrogen atoms slightly positive charges). When you put salt in water, the ionic bond between the positive sodium and the negative chloride breaks. The positive sodium atom is pulled to the negative end of the water molecules, and the negative chloride atom is pulled to the positive end of the water molecule.
If you put salt into water then the water will boil a little faster, but not much.
the water evaporates and then it leaves the salt behind
Salt remain as a residue.
It makes salt and water!
the rock salt dissolves in the water
The salt dissolves in the water and the iron does not.
Salt water is still salt water no matter where it goes as long as there is still salt in the water.
You get salt water.
it becomes salt water
salt
it dissolve in the water
the water evaporates and then it leaves the salt behind
You get a mixture of salt and sand. Nothing more happens.
The salt dissolves in the water
You create a solution of the salt in water.
Nothing happens.
Salt is not evaporated !
You get a salt solution.
