Water Quality Parameters: pH

Backing up to the previous section, let’s recall what makes up water. Two charged particles: H+ and OH- are what make up pure water. Remember that water in the environment is never pure; it is an aqueous solution containing many dissolved salts and even gases. The pH of a solution is a measure of the […]

Molecular Attraction & Phases of Water

Unlike most substances, water is commonly found in all its phases (solid, liquid, and gas) on earth. The unique properties of each of the phases also contribute to many aspects of life. For instance, the maximum density of water occurs at about 4.0 Celsius (Density = 0.9998 g/mL), and water is less dense upon freezing (Density […]

The MSP project is funded by an ESEA, Title II Part B Mathematics and Science Partnership Grant through the Montana Office of Public Instruction. MSP was developed by the Clark Fork Watershed Education Program and faculty from Montana Tech of The University of Montana and Montana State University, with support from other Montana University System Faculty.
