Dissolve experiments

Dissolve experiment 

Aim: to see if salt or baking soda dissolves the most 

Hypothesis: I believe the baking soda will dissolves more as it is much smaller than a grain of salt

Equipment: a 250 mL beaker 100 mL measuring cylinder salt baking soda a stirring rod a teaspoon and a ruler 

Methold: 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 a ruler across the edges of the teaspoon

3. Stir the solution until all of the baking soda has dissolved  

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

5. Record how many teaspoons of baking soda were added

6. Repeat the experiment with table salt

Results 

solute	Number of teaspoons that dissolved in 80 mL of water
Baking soda	3
Table salt	8

Discusion me and my group started talking about if how fast you stirred would dissolve the chemicals faster and if we spearted the teaspoons more that the baking soda would dissolve faster
