Improving Conceptions in Analytical Chemistry: c_{i} V_{i} = c_{f} V_{f} Margarita RodríguezLópez and Arnaldo Carrasquillo Jr. A common misconception related to analytical chemistry, which may be generalized as the failure to recognize and to account analytically for changes in substance density, is discussed. A cautionary example is made through the use of massbased units of composition during volumetric dilution. The correct application of the volumetric dilution equation ci Vi = cf Vf is discussed. A quantitative description of the systematic error introduced by incorrect use of the volumetric dilution equation is also specified. RodríguezLópez, Margarita; Carrasquillo, Arnaldo, Jr. J. Chem. Educ. 2005, 82, 1327.

The chemical equation. Part I: Simple reactions Kolb, Doris A chemical equation is often misunderstood by students as an "equation" that is used in chemistry. However, a more accurate description is that it is a concise statement describing a chemical reaction expressed in chemical symbolism. Kolb, Doris J. Chem. Educ. 1978, 55, 184.
