Solutions

Aim: 

To investigate the solubility of Calcium Chloride and Magnesium Oxide.

Equipment:

• Spatula 
• A stirring rod
• Beaker
• Measuring cylinder
• Calcium Chloride
• Magnesium Oxide

Method

1. Fill the beaker with 100mL of tap water
2. Add a spatula scoops of the Calcium Chloride
3. Stir the solution until all of the Calcium Chloride has dissolved
4. Repeat steps 2 and 3 until no more of the Calcium Chloride will dissolve
5. Record how many spatula scoops of Calcium Chloride were added
6. Repeat experiment with the Magnesium Oxide

Magnesium Oxide

Magnesium Oxide = 5 spatula scoops

Calcium Chloride = 7 spatula scoops

Calcium Oxide
