Creating a sucrose solubility curve

 20 Points

You can work in groups of up to 4, however each student must turn in a report for credit.

1.    Obtain a cup of sucrose.  Weigh the cup and record the mass in the table.

2.    Obtain a test tube.  Place 10 mL of water in it.  Label it with your name.

3.    Begin to dissolve the sucrose in the water.  Stop adding sucrose when you first see undissolved crystals at the bottom.

4.    Record the temperature of the water.  Weigh the cup and record the mass in the table below.  

5.    Place the test tube in the hot water bath.  The instructor will help with this.

6.    After a few minutes, check the temperature of the water in the test tube.  If it has increased by 20 degrees, repeat steps 2-4.

7.    Obtain 4 data points.

Multiply the mass dissolved by 10 to compute the solubility in g/100mL.

Draw the solubility curve for sucrose and attach it to this sheet.

The curve which is closest to the standard will receive 10 extra credit points.
