Investigating Solubility

SOLUBILITY EXPERIMENT

Aim:

To investigate the solubility of baking soda, table salt and copper oxide to see which is the most soluble

Equipment:

100mL beaker, 100mL measuring cylinder, salt, baking soda, copper oxide, stirring rod, spatula.

Method:

1. Fill the beaker with water
2. Add a spatula full of baking soda.
3. Stir the solution until it dissolves.
4. Repeat step 2 and 3 until no more will dissolve.
5. Record how many spatula fulls were added.
6. Repeat the experiment with salt and copper oxide.

2 full spatula of baking soda 

My experiment failed because the water did not turn into a clear water.
