Polarity of Water

The partial charges and dipole for the water molecule are shown in Figure 4.5; note that the charges are significantly larger than in carbon monoxide. These partial charges result in water molecules being strongly attracted to one another in the solid and liquid phases. In other words, for a group of water molecules, the positively […]

Polar Molecules

One of the main reasons water will dissolve so many compounds is that the water molecule is polar. In chemistry, polarity refers to a separation of electric charge leading to a molecule having an electric dipole. Consider a simple linear molecule like carbon monoxide (which can be quite toxic in enclosed areas, e.g. tents and garages), […]

Structure & Properties of Water

The noblest of the elements is water. -Pindar, Greek Poet, 476 B.C. Of course, water is not an element, and almost everyone knows the chemical formula for the compound water: H2O. Many also know its bend arrangement, the atoms forming the H-O-H bonds. In Figure 1.1, both the bond angles and bond distances are represented. […]

An Introduction to Water

Anyone who can solve the problems of water will be worthy of two Nobel prizes – one for peace and one for science. -John F. Kennedy Water (H2O) is the most common substance on Earth, covering about 75% of the surface and existing in a solar-driven flux between the gas, liquid and solid phases. Of […]

Module 4:
Water

After completing this module, you will be able to: Describe the chemical and molecular properties of pure water and how they relate to water in the environment (e.g. the water cycle); Plan and conduct basic water quality monitoring using World Water Monitoring Day field kits in a sound scientific method to assess water quality; Communicate […]

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.
