Water conductivity in stream environments. Background. Conductivity, a meaure of electrical current flow through a solution, is expressed in units of microSiemens (uS). Conductivity is the reciprocal of electrical resistance (ohms). Because conductivity increases nearly linearly with increasing ion concentration, we can use conductivity measurements to estimate ion concentrations in solutions

Within thermodynamics, a physical property is any property that is measurable, and whose value describes a state of a physical system. Some constants, such as the ideal gas constant, R, do not describe the state of a system, and so are not properties.On the other hand, some constants, such as K f (the freezing point depression constant, or cryoscopic constant), depend on the identity of a

Positive and Negative Ions: Cations and Anions dummies

Cations (positivelycharged ions) and anions (negativelycharged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride. A metal reacts with a nonmetal to form an ionic bond.

How are salts harmful to plants? ucanr

Another way salts in the soil water can affect the growth of plants is by specific ion toxicities. Ions are atoms or groups of atoms with a net positive or negative charge.
