Analysis of Iron in Lawn Fertilizer: A Sampling Study
Jeannot, Michael A.
Journal of Chemical Education, v83 n2 p243 Feb 2006
An experiment is described which uses a real-world sample of lawn fertilizer in a simple exercise to illustrate problems associated with the sampling step of a chemical analysis. A mixed-particle fertilizer containing discrete particles of iron oxide (magnetite, Fe[subscript 3]O[subscript 4]) mixed with other particles provides an excellent demonstration of sampling uncertainty.
