n: the combining power of a base, or alkali, as measured by the number of equivalents of an acid with which it reacts to form a salt. Any solution that bas a pH greater than 7 is alkaline. See pH.

n: The combining power of a base measured by the maximum number of equivalents of an acid with which it can react to form a salt. In water analysis, it represents the carbonates, bicarbonates, hydroxides and occasionally the borates, silicates and phosphates

a resin formed by reaction of polyhydric alcohols and polybasic salts. Saturated or unsaturated oils or fats are involved.

n: an aluminum salt of stearic acid used as a defoamer. See stearate.

a mud degasser chemical.

n: A colloidal, viscosity-building clay used principally in salt-water muds.

a colloidal, viscosity building clay used in water based muds. They generate viscosity due to the mechanical interference of their straw shaped bodies.

n: A kind of baculate clay, sometimes called salt-resisting clay or brinish clay because it is easy to slake in the brine and it is high yield.

n: the depositional environments associated with a shallow lagoon shoreward from a coastal barrier island. These environments are highly variable and may include tidal channels, salt marshes, shell reefs, and mangrove swamps, among others.

n: any shipboard tank or tanker compartment normally used for carrying saltwater ballast. When these compartments or tanks are not connected with the cargo system, they are called segregated ballast tanks or systems.

n: an extrusive igneous rock that is dense, fine grained, and often dark gray to black. Compare gabbro.

the most common volcanic rock. Usually fine grained.

n: a substance capable of reacting with an acid to form a salt. A typical base is sodium hydroxide (caustic),with the chemical formula NaOH. For example, sodium hydroxide combines with hydrochloric acid to form sodium chloride (a salt) and water. This reaction is written chemically as NaOH + HCl -+ NaCI + H2O.

n: water that contains relatively low concentrations of soluble salts. Brackish water is saltier than fresh water but not as salty as salt water.

n: The water which contains lesser salt, including hard water whose pH is from 7 to 9. Usually the content of chloride is less than 18970g/L. It comes from coastal waters, bay, variole or inland lake. This kind of water contain more Ca2+ and Mg2+. We should

indefinite term meaning water with small amounts of salt. Saltier than fresh water.
