HTH Field Trips to Students to Science 7 & 11 December 2012 Dr. Cincottas 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 an Unknown 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. Electrochemistry Building 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 Sweetener Identifying 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 many Valuable 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.
