When salt is dissolved in water, it is in a dissolved state where the salt particles break apart into ions. This creates a solution where the salt ions are surrounded by water molecules.
Students will make a 2-D model of a salt crystal and use water molecule cut-outs to show how water dissolves salt. After seeing an animation of water dissolving.
Salt
The binding energy of the molecule compared to the binding energy of the ions it splits into when it is dissolved determines the change in heat of the water. The stronger a molecule is bound, the higher its binding energy and the more heat is needed to break it apart, which cools the water.
When salt has dissolved, the reading of the balance will remain the same as before the salt dissolved. The mass of the salt is still present in the solution, even though it is no longer visible as solid particles.
Salt, sugar and baking soda.
Salt water works because electricity needs a conduit to get electrons from one place to another. Salt is a molecule that is able to do this when it is dissolved in water.
When salt is dissolved a water sodium chloride solution is obtained.
95% of Earth's water contains high concentration of salt, or high salinity
No, a salt is a compound. A salt maybe dissolved in water and made into a solution but as salt is not a solution per se.
The separated salt is a crystalline solid; the dissolved salt is dissociated in ions.

salt when dissolved in water will become an acidic solution
