CHE 230: Chemical Analysis: The Proposal and ACS Style

This guide includes resources helpful to students working on the CHE 230 Library Assignment

Adding citations to Endnote

Your Proposal

Your proposal is due on March 23rd. This proposal must include and describe

  • Analyte of interest
  • Matrix to be analyzed
  • Experimental protocol – are you comparing two sample prep techniques or two analysis techniques?  What is your hypothesis?
  • Experimental details
    • all reagents, supplies, equipment, instrumentation needed
    • number or replicates for statistical analysis
    • sampling of matrix & sample size
    • sample preparation (Do you have to grind sample?  Extract analyte?)
    • detailed procedure (bulleted form ok)
    • standard preparation, calibration
  • Reference value for comparison (so you know what concentration to expect)
  • References (using standard guidelines, MLA, ACS, etc.)



ACS Style

ACS Style is a suggested structure and set of guidelines (including citation style) for articles in the field. 

In-text citations

For ACS Style you use superscript numbers within or after cited information

Example: Fluoridated water as well as various fluoride products such as toothpaste provide fluoride ions necessary for remineralization.¹

The number you use will correspond to the citation you are referring to.
