Investigation 1: SOLUBILITY
Aim: To find the amount of salt/sugar that can dissolve in 100g of water.
Lesson Objective: To determine how much solute dissolves in 100g of solvent and factors affecting
solubility
Materials: salt, sugar, water
Apparatus: beaker, stirring rod, bunsen burner, weighing balance
Method:
1) Prepare two beaker and measure is weight and label beaker A and beaker B.
2) Measure 100cm3 of water (equivalent to 100g) using a measuring cylinder and pour in the
beaker A. Weight the beaker with water.
3) Now add salt/sugar into the flask slowly and stir until no more dissolves.
*Stirring the solvent is a factor that help to dissolve more solute.
4) When no more salt/sugar dissolves then filter the solution into beaker B. This is to remove
excess/extra solute.
5) The solution in beaker B is weighed to find out the mass of salt/sugar solution.
Results:
