How to dissolve salt in water
Choose a salt.
There are many different salts available, and they all have different properties. The amount of epsom salt (mgso) that you can dissolve into a given amount of water at a given temperature will differ from the amount of table salt (nacl) that you can dissolve into the same water.

If you are trying to understand the dissolution process in general, you should stick with using table salt since the particles are smaller and will therefore dissolve easier. If you need to study the properties of a specific salt, use that salt.
