Solubility Experiment

Aim: To investigate the solubility of baking soda and table salt to see which is the most soluble in water.

Hypothesis: I think the baking soda will be most soluble in water. 

Equipment: 

1. 100ml beaker
2. 100ml measuring cylinder 
3. Stirring rod 
4. Teaspoon 
5. Baking soda
6. Salt

Method:

1. Fill a beaker with 80ml of water.
2. Add a level teaspoon of baking soda.
3. Stir the solution until all the baking soda has dissolved. 
4. Repeat step 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 for the table salt. 

Results: 

Solute	Number of teaspoons that dissolved in 100ml of water
Baking soda	5
Table Salt	3

Discussion: 

Our results are saying that baking soda is more soluble in water than what table salt is. The first time we did this experiment we started with table salt but didn't have enough time so we could have added more salt in. Also next time I should pay attention to the water temperature. Warm/hot water is better than cold water when trying to dissolve something.  We added in 3 teaspoons of table salt which dissolved 15 grams in total. We added in 5 teaspoons of baking soda which dissolved 25 grams in total. 

Conclusion:

Our experiment worked as it told us what ingredient is more soluble in water. My hypothesis was correct as I said baking soda is more soluble in water than what table salt is.
