Homepage -- Fall 2011 updated 10/12/11

This is the first term of the Junior level Integrated Laboratory sequence for chemistry majors. Students learn to integrate experimental techniques and ideas from analytical, inorganic, organic and physical chemistry to solve multidiscipline problems. Small class size of 21 students. E.Chem I, CH 362, is a prereq and co-requisites are CH 421 and CH 440 (can be taken simultaneously with CH 461 lab).
