Separation of Powders

The purpose of this experiment is to test the solubility of salt and sand in water, and determine whether or not salt is soluble, sand is soluble, or both sand and salt are soluble.

What is solubility?

"The solubility of a substance is the amount of that substance that will dissolve in a given amount of solvent. Solubility is a quantitative term. The terms soluble and insoluble are relative. A substance is said to be soluble if more than 0.1 g of that substance dissolves in 100 mL solvent. If less than 0.1 g dissolves in 100 mL solvent, the substance is said to be insoluble or, more exactly, sparingly soluble." (Rogers, 2000). In order for a substance to be considered soluble, it has to be able to be dissolved in a liquid. In this experiment, the substances that are being tested for solubility are sale and sand, and the solvent is water. To determine whether or not the substances are soluble, they will be put through a filtration process, and the insoluble material will be left behind. The filtration process in this experiment will be a coffee filter, which will be secured for stability, and the insoluble material will be collected here.
