Solubility Experiment - Science

Solubility Experiment

Aim: To see if salt or baking soda dissolves more in water.

Hypothesis: I don't have any theories but I think the baking soda will dissolve faster but it will turn to paste but that is it changing from it's original form so it had dissolved. 

Equipment: A 250mL breaker, 100mL measuring cylinder, salt, baking soda, a stirring rod, a teaspoon and a ruler.

Method: 

1: Fill the breaker with 100mL of tap water.

2: Add a level teaspoon of baking soda. A level teaspoon is obtained by running your ruler across the edge of the teaspoon.

3: Stir the solution until all of the substance has dissolved. 

4: Repeat steps 2 and 3 until no more baking soda will dissolve into the solution.

5: Record how many teaspoons of baking soda were added.

6: Repeat the experiment again with salt. 

Results: 

Solute	Number of teaspoons that dissolved in 100 mL of water.
Baking Soda	3
Salt	7

Discussion: Salt took more spoonfuls to stop dissolving. The baking soda took longer because it's attraction to water was less than salt and water.

Conclusion: The experiment did end up being successful. My hypothesis was incorrect but I was right about the baking soda dissolving faster.
