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

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.
