1 HTH Field Trips to Students to Science 7 & 11 December 2012 Dr. Cincottas Chemistry Classes

2 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

3 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.
