HTH Field Trips toStudents to
Science7 & 11 December 2012
Dr. Cincotta’s Chemistry Classes
Students Spent 4 Hours Performing
Hands-on Experiments
1. Identifying an Unknown Salt
2. Electroplating Copper
3. Identifying an Unknown Artificial Sweetener by:
the presence or absence of a carbonyl group
the presence or absence of sulfur
1. Identifying anUnknown Salt
Using the flame test to identify the cation
Using double replacement reactions to identify the anion
Using these techniques to identify the salts used in various brands of low-salt chips.
2. ElectrochemistryBuilding an electrolytic cell
Identifying spontaneous single replacement reactions (non-electroplating)
Electroplating copper onto a nickel
Determining the amount of copper plating
3. Identifying an Unknown
Artificial SweetenerIdentifying the functional groups present in each sweetener
Combusting each sweetener
Titrating the ash for sulfur to identify sulfonyl groups
Performing Infrared Spectroscopy to identify the presence of carbonyl groups
Identifying each unknown sweetener based on the presence or absence of carbonyl and sulfonyl groups
There were manyValuable
Opportunities to Interact with Professional
Scientists, all of whom Volunteered to
be with us.Training in the Use of Sophisticated Equipment and Experimental Technique
Analyzing Data
Discussions about Science and Careers in Science
And just having Fun in the lab!
Thank you!To the Hudson County Schools of Technology Foundation for providing 100% of the funding for this valuable experience.
To the two dozen professional scientists and staff of Students to Science, Inc. for volunteering their time and talents to spend a day in the S2S lab with us.
Your generosity gave us a unique and outstanding educational experience.
