Solubility Experiment

Aim:
To find out which of salt or baking soda will dissolve more.

Hypothesis:
In my opinion, I think salt will dissolve more than baking soda depending on the heat of the water.

Equipment:
1. 250ml Beaker
2. 100ml measuring cylinder
3. Salt
4. Baking soda
5. Stirring rod
6. Teaspoon

Method:
1. Fill the beaker with 100ml of tap water.
2. Add a leveled Teaspoon of baking soda, (with the Bs the same level of the rim of the spoon.) 
3. Stir until all is dissolved
4. Repeat steps no. 2 & 3 until no baking soda needs to be dissolved.
5. Write down how many teaspoons of baking soda was used.
6. Repeat the experiments with the table salt.


Solute
No. of Teaspoons
Baking Soda
17
Salt
22

Discussion:
This experiment was to figure out which of our substances would whether or not become a solvent. This was also to investigate which substance would dissolve more.

Conclusion:
Image result for solubilityMy hypothesis was that salt would dissolve faster, as it was always used in cooking and would normally always dissolve. But really sometimes it depends on the heat of the water. It turn out I was right salt dissolves more than the other substance.

This was a really fun experiment and went smoothly, as it was an easy experiment. It was simple since you didn't have to be so precise with the measurements.  All you needed to do was count the spoons of the substance you put into the solvent.

In the results for the baking soda, it started to form clumps at the bottom of the beaker and made the water look like soapy water,  Same happened with the salt.
