Dissolving solids in water
Water is an extremely important and effective solvent for many of the substances found in food.
How many grams of a particular substance will dissolve in a given amount of water depends on two factors.
The first is the substance itself, and the second is the temperature of the water.
In this experiment, you will compare the solubility of three compounds.
Solubility is the maximum amount of solute that can be dissolved in a definite amount of solvent at a specific temperature.
You will find out how much sucrose (sugar), sodium chloride (tablesalt), and potassium nitrate can dissolve in 10 mL of water at room temperature (20 C) and and at 80 C.
