Solubility Dissolving Experiment

Aim: See if salt or baking soda dissolves more

Hypothesis: I think that the Baking soda will dissolve more than Salt because it's powder and it is thinner when it is dissolving in liquid and salt is a bit more thicker.

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

Method:
1. Fill the beaker with 100 ml of tap water
2. Add a level teaspoon of baking soda. A level teaspoon is obtained by running your ruler across the edges of the teaspoon).
3. Stir the solution until all the baking soda is dissolved.
4. Repeat step 2 and 3 until no more baking soda will dissolve into a solution.
5. Record how many teaspoon of baking soda were added.
6. Repeat the experiment with the table of salt.

Result:

Solute	Number of teaspoon that dissolved in 100 ml of water
Baking Soda	2 teaspoon
Table Salt	5 teaspoon

Discussion:

This experiment involved dissolving a solute. The first substance that we used was table salt, the result that it got up to was 5 teaspoons while the Baking soda only got up to 2 teaspoon. I'm pretty happy with the results that we got.

Conclusion:

The Hypothesis that I made was wrong. The salt ended up dissolving much better and quicker than the Baking soda. I thought that Baking soda was going to dissolve better because it's particle size is much more smaller than the table salt.
