The properties above were described. We can also compare the properties of substances by measuring them. In this chapter we will take measurements for the following physical properties: Solubility Conductivity Melting point Boiling point
21.2 Solubility
Solubility is a measure of how much of a substance will dissolve in another substance. Solubility is usually measured as grams of solute per 100 cm3 is 204 g of sugar per 100 cm3
of water at 20o C.
Activity Compare the solubility of a range of chemicals in water
Apparatus Five test tubes, test tube rack, thermometer, spatula, electronic balance
