Dissolving Solution

Aim

To investigate the solubility of Calcium Chloride and Magnesium Oxide to see which is the most soluble in water.

Equipment

-A 250ml Beaker

-100ml Measuring Cylinder

-Calcium Chloride

-Magnesium Oxide

-A Stirring Rod

-A Spatula

Method

-Fill the Beaker with 100ml of tap water

-Add a bit Calcium Chloride by using a Spatula

-Stir the solution until all of the Calcium Chloride has dissolved

-Repeat steps 2 and 3 until no more Calcium Chloride will dissolve into the solution

-Records with how many Calcium Chloride you added with the spatula.
-Repeats the experiment, with Magnesium Oxide

Results

Solute

-Calcium Chloride-2

-Magnesium Oxide-6

Discussion 

-It took really long to dissolve Calcium Chloride.

-It took less time to dissolve magnesium Oxide and more to dissolve.
