WebYou should have noticed that sugar had the highest solubility of all your tested compounds (sucrose: about 200 grams per 100 mL of water), followed by Epsom salt (Magnesium sulfate heptahydrate: 113 grams/100 mL), table salt (NaCl: 35.17 g/100 mL), and baking soda (NaHCO 3: 9.6 g/100 mL). WebSolubility is a term used to describe the amount of materials (solids, liquids, or gas) which can be dissolved in a solvent to make a solution. A solvent is the dissolving agent, e.g. water. A solute is a substance that is dissolved in a solution. In this science fair project, solutions in which the solvent is a liquid will be investigated.
