Ion Exchange Treatment
A common water-softening method often found on a large scale at water purification plants that remove some organics and radium by adding calcium oxide or calcium hydroxide to increase the pH to a level where the metals will ...
ion. An electrically charged atom, radical (such as SO42-), or
molecule formed by the loss or gain of one or more
electrons.
Complex Ion
A metal ion with Lewis bases attached to it through coordinate covalent bonding.
Compliance Monitoring ...
ligand
Ion, molecule, or molecular group that binds to another chemical entity to form a larger complex.
limacide
Substance intended to kill mollusks including the gastropod mollusk, Limax.

Neutral pH is not exactly 7; this would imply that the H+ ion concentration is exactly 1×10-7 mol/L, which is not the case. The value is close enough, however, for neutral pH to be 7.
Soil acidity (or pH) is defined as the logarithm of the reciprocal of the Hydrogen ion (H+) activity or pH = -log Activity H+, but in practice this equation is usually circumvented by the use of a soil pH meter.
The negative logarithm of the ratio of the hydrogen ion activity to the square root of the sum of the activities of calcium and magnesium in the soil solution. It is generally written as pH - 1/2p(Ca + Mg).
Air polluted with carbon dioxide is pumped into the CO2 scrubber wherein an ion exchange resin attracts carbon dioxide molecules. After this, the carbon-free air is released out of the scrubber.
Electrical charge: The charge on an ion, declared by its number of electrons. A Cl- ion is in fact a Cl atom which has acquired an electron, and a Ca++ ion is a Ca atom, which has lost two electrons.
- A number denoting the common logarithm of the reciprocal of the hydrogen ion concentration. A pH of 7.0 denotes neutrality, higher values indicate alkalinity, and lower values indicate acidity.

Analyte: The element or ion an analysis seeks to determine; the element of interest.
Ammoniacal nitrogen
nitrogen combined with hydrogen in the form of ammonia (NH3) or the ammonium ion (NH4+); present in sewage, toxic to fish and restricted in discharges to about 5-0-10-0 mg/l ...
