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:
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.
