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: sodium hydroxide, NaOH. It is used to maintain an alkaline pH in drilling mud and in petroleum fractions.

n: See sodium hydroxide.

sodium hydroxide.

n: a compound that is formed (along with water) by the reaction of an acid with abase. A common salt (table salt) is sodium chloride, Naa, derived by combining hydrochloric acid, Ha, with sodium hydroxide, NaOH. The result is sodium chloride and water, H2O. This process is written chemically as Ha + NaOH ~ NaCI + H2O. Another salt is calcium sulfate, CaS�4, obtained when sulfuric acid, H2SO4 is combined with calcium hydroxide, Ca (OH)2

n: see caustic soda.

n: The common name for sodium hydroxide [NaOH]. Caustic soda is used in most water-base muds to increase and maintain pH and alkalinity. It is a hazardous material to handle because it is very caustic and gives off heat when dissolved in water. Proper traini

n: A group of salts formed by neutralization of phosphorous or phosphoric acid with a base, such as NaOH or KOH. Orthophosphates are phosphoric acid (H3PO4) salts, where 1, 2 or 3 of the hydrogen ions are neutralized. Neutralization with NaOH gives three sod

n: Linear, anionic polymer made from the monomer acrylic acid, CH2=CHCOO- H+. The acrylic acid groups are evenly spaced along the chain. Acrylic acid polymer neutralized with NaOH is sodium polyacrylate (SPA). Polyacrylates are best utilized in soft water wi
