We begin this section with a deceptively simple question. What is analytical chemistry? Like all fields of chemistry, analytical chemistry is too broad and active a discipline for us to easily or completely

Fundamental Units of Measure SI units Stands for Système International d’Unités. These are the internationally agreed on units for measurements. Imagine that you find the following instructions in a laboratory

Chemistry is the study of matter, including its composition,structure, physical properties, and reactivity. There are manyapproaches to studying chemistry, but, for convenience, wetraditionally divide

2B.1 Molarity and Formality Both molarity and formality express concentration as moles of solute per liter of solution. There is, however, a subtle difference between molarity and formality. Molarity is

Normalityis an older unit of concentration that, although once commonly used, isfrequently ignored in today’s laboratories. Normality is still used in some hand-books of analytical methods, and, for this

Conservation of Protons In an acid–base reaction, the reaction unit is the proton. For an acid, the number of reaction units is given by the number of protons that can be donated to the base; and for a

Conservation of Electrons In a redox reaction, the reaction unit is an electron transferred from a reducing agent to an oxidizing agent. The number of reaction units for a reducing agent is equal to the

Conservation of Electrons In a redox reaction, the reaction unit is an electron transferred from a reducing agent to an oxidizing agent. The number of reaction units for a reducing agent is equal to the

Conservation of Charge The stoichiometry between two reactants in a precipitation reaction is governed by a conservation of charge, requiring that the total cation charge and the total anion charge in

Conservation of Protons In an acid–base reaction, the reaction unit is the proton. For an acid, the number of reaction units is given by the number of protons that can be donated to the base; and for a

Conservation of Mass The easiest principle to appreciate is conservation of mass. Except for nuclear reactions, an element’s total mass at the end of a reaction must be the same as that present at the
