CHEM 311 Environmental Chemical Analysis
UNITS OF CONCENTRATION
There are a number of different ways of expressing solute concentration that are
commonly used. Some of these are listed below.
Molarity, M = moles solute/liter of solution
Normality, N = equ
Rules For Assigning Oxidation States
1. For free elements the oxidation state is zero.
Fe(s), O2(g), O3(g), H2(g), Hg(l), Hg(g), S(s) etc.
2. For monoatomic ions, the oxidation state is given by the charge on the ion.
Cl- (-1), Fe2+ (+2), Fe3+ (

Rules for Reporting Significant Figures
Nonzero digits always count as significant figures
Zeros are what mix people up. There are three situations in which they can occur.
leading zeros precede all nonzero digits and are never significant (i.e., 0.
