Question:

Are ionic compounds more soluble than covalent compounds?

 

Hypothesis:

According to Mr. Person Ionic compounds should be more soluble than covalent compounds. 

 

Materials:

• Triple Beam Balance

• graduated cylinder

• 100 ml beaker (2)

• salt

• sugar

• distilled water

• spatula

 

Procedure:

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

2. Measure 50g of salt in a triple beam balance

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

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

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

 

Data:

Compound                      Original mass                     Remaining Mass (g)                     Amount Dissolved (g)   

Salt                                         59.5g                                          40g                                                10g

Sugar                                      59.9g                                          11.3g                                             48.6g                                                                                            

 

Analysis

More sugar desolved than salt.

 

Conclusion

We did as we were meant to and we found our answer reasonable. We found the remaining mass for salt higher than the remaining mass for sugar. This assignment I also did in the UK. It is fun but can be hard at times.
