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

process where a special resin exchanges chloride or hydroxide for contaminant anions such as fluoride, nitrate, sulfate and bicarbonate. Water purification is the primary use.

n: See sodium bicarbonate.

bicarbonate of soda, used in acid neutralization operations.

a compound containing the HCOO- ion.

Soda ash, bicarbonate of soda, caustic soda and some phosphates. Act to reduce the effects of calcium in a fluid.

19359 mg/l chloride;2702 mg/l sulfate;142 mg/l bicarbonate;11155 mg/l sodium + potassium;1297 mg/l magnesium;408 mg/l calcium;TDS = 35169 mg/l;pH = 8.2.

n: see sodium carbonate.

n: No-water sodium bicarbonate,white powder or micro-grain.


sodium carbonate.

n: the half-neutralized sodium salt of carbonic acid, NaHCO2, used extensively for treating cement contamination and occasionally other calcium contamination in drilling fluids.

n: A chemical with the formula NaHCO3. It is called bicarb at the drilling rig and is used to treat cement contamination in water mud. When cement hydrates, substantial amounts of lime, Ca(OH)2, are produced. As the cement sets, less free lime is available.

used for treating cement contamination and calcium contamination in muds.

n: Na2CO3, used extensively for treating various types of calcium contamination. Also called soda ash.

n: A chemical with the formula Na2CO3. It is called soda ash at the drilling rig and is used to treat most types of calcium ion contamination in freshwater and seawater muds. For cement contamination, sodium bicarbonate is used. Calcium ions from drilling gy
