Does the Solubility of Solid Salt Increase With the Volume of Water?

Hi, I'm Sean Tvelia and we're here at Suffolk County Community College today to see what happens to solubility if we increase the volume of water. So to start let's talk about solubility. Solubility is a measure of the maximum amount of material that can be dissolved into another material. So for today's experiment we are going to need simple table salt, sodium chloride and water. The solubility of sodium chloride is roughly 35 grams per 100 milliliters of water. So that is the solubility of water. We'll start by dissolving 35 grams of salt in the 100 mgs. of water. And then we will increase the volume of water and use an additional amount of salt to see if we can increase the solubility by adding additional water. What we will notice since solubility is a measure of the maximum amount of material that can be dissolved in a solvent, by adding additional water we will not see any increase in the solubility. We'll see just simply double the amount of solute for double the amount of solvent.
