Addendum to "Laser-Pointer-Based Spectrometer for Endpoint

Chemical Education Today

Letters Addendum to “A Laser-Pointer-Based Spectrometer for Endpoint Detection of EDTA Titrations” It has come to my attention that a paper that I recently published in the Journal (1) should have referenced an article previously published in the Journal by Mehta and Dallinger (2) entitled “A Colorimetric Titration Experiment with Laser Excitation and Computer-Interfaced Endpoint Detection”. I would like to thank Dr. Dallinger for bringing this to my attention and I apologize for not including his paper.
