My Hypothesis:

My hypothesis is that the ionic compound is more soluble than the covalent compound. I think that suger will disolve more than salt.

Materials:

• Triple beam balance

• Graduated cylinder 

• 100ml beaker (2)

• Salt

• Sugar

• Distilled water

• Spatula

 

Procedure:

1. Measure 60ml of distilled in a graduated cylinder and pour into a 100ml beaker

2. Measire 50g 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 remaning salt and subtract from 50g to determine how salt was desolved, record.

5. Repeat steps 1-4 with sugar and a second 100ml beaker :)

 

Data:

Compound          Orignal Mass (g)      Remaning Mass (g)       Amount Dissolved (g)          
Salt                            50g                                   31g                                     19g 

Sugar                        50g                                    30.3g                                 19.7g

 

Conclusion: Salt and Sugar are both equally soluble. Some might disolve faster and the others longer. At the end they are both equally soluble.
