Problem:

Do ionic compounds or covalent compounds dissolve faster? 

 

Materials: 

• Graduated cylinder

• 2 cups

• Triple Beam Balance

• Salt

• Sugar

• Distilled water

• Spatula

 

Procedure:

1. Measure 60ml (milliliters) distilled water in a graduated cylinder and pour into a 100ml beaker.

2. Measure 50g (grams) of salt on a triple beam balance.

3. Slowly add salt to the distilled water, stirring constantly, until the salt won’t dissolve anymore.

4. Determine the mass of the remaining salt and subtract from 50g to determine how much salt was dissolved.

5. Repeat steps 1-5 with sugar and a second 100ml (milliliters) beaker.

 

Conclusion: 

 

In my conlusion, we figured that the salt was more solluable than the salt so our hypothesis was wrong. Our hypothesis was wrong because we thought that the salt with the water would be more solluable but that turned out wrong. 

 

Additional Questions: 

 

1. What would happen if we added more sugar to the experiment? 

 

What would happen if we added more sugar to the experiment, is that it would have been harder for it dissolve.

 

2. What would happen and what would change if we added more water to this experiment? 

 

What would happen and what would change if we added more water to this experiment, is that it would have been faster and easier for both the salt and the sugar to dissolve. 

 

Results: 

 

Salt that was left: 41.5g

Salt that was used: 8.5g

 

Sugar that was left: 0

Sugar used: 50g
