How to Dissolve Salt in Water: 9 Steps (with Pictures) - …

27/2/2020· For example, sodium chloride (table salt) has a solubility in water of 359g/L, so you can dissolve 359g of salt in a liter of pure water. Any more won''t dissolve. You can heat it up, which will make more of it dissolve, but when it cools down you will have a supersaturated solution, where the salt will spontaneously crystalize if the solution is disturbed.
