How do you do an experiment to show that when you dissolve salt in water the salt is still there?

Answer 1

Either you have added too much salt or not enough water or the water is too cold. You could begin again and see if that changes. Otherwise continue since the solution is supersaturated.

Answer 2

To show that salt is still present in water after dissolving, you can evaporate the water and observe the salt residue left behind. Start by weighing the original amount of salt, dissolve it in water, then heat the solution until all the water evaporates. Finally, measure the remaining salt residue to confirm that the salt did not disappear during the dissolving process.
