Physical Properties of Water,e water molecule is dipolar—there are negatively and positively charged sites on opposite sides of the molecule. As a result, water molecules form hydrogen bonds with other water molecules. Hydrogen bonds are stronger than van der Waals attractions that occur among molecules, and impart unique physi

The TDS concentrations in natural freshwaters typically range from about 20–1,000?mg/L; the solids consist mainly of bicarbonate (and carbonate at pH above 8.3), chloride, sulfate, calcium, magnesium, potas

Suspended particles vary from tiny colloids (1–100?mμ) that remain suspended indefinitely in still water to larger silt and sand particles held in suspension by

Concentrations of dissolved oxygen at saturation decrease with greater elevation (lower barometric pressure), higher salinity, and rising temperature. The concentration of dissolved oxygen in water may be exp

Redox Potential,s—in which one substance, the oxidizing agent, accepts electrons from another substance, the reducing agent. The oxidizing agent is reduced and the reducing agent is oxidized. The flow of electrons between two half-cells can be measured as an electromotive force (in volts). The hydrogen half-cell (H
