Investigating solubility

Aim:
I want to investigate the solubility of calcium chloride and magnesium oxide to see which is more soluble in water.

Equipment:

• calcium chloride
• magnesium oxide
• 100mL measuring cylinder
• stirring rod
• 250mL beaker
• spatula

Method:

1. fill a beaker with 100mL of tap water.
2. get your spatula and scoop some calcium chloride into the beaker.
3. stir until the solution is dissolved.
4. Repeat steps 2 and 3 until its insoluble (keep data of how many scoops you applied).
5. Repeat experiment but with magnesium oxide.

Results:

I was able to get 12 scoops of calcium chloride until it was insoluble. Magnesium oxide is insoluble
