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

n: An additive that adjusts acidity and alkalinity of the drilling fluid.

n: the measured neutro ability to acid of the fluid filtrate

n: a drilling fluid with a pH range above 10.5, i.e., a high-alkalinity mud. high-pressure area n: an area of high atmospheric pressure.

n: a measure of the acidity or alkalinity of a solution, normally expressed as pH. See pH.

n: a measure of the acidity or alkalinity of a solution, normally expressed as ph. See also ph

n: the methyl orange alkalinity of the filtrate, reported as the number of millimetres of 0.02 normal (N/50) acid required per millimetre of filtrate to reach the methyl orange end point (pH 4.3). M1 is a measure of the alkalinity of the drilling fluid. Usually, drilling fluids should have a high pH value (alkalinity) to ensure that they perform as they should.

n: see M1.

n: indicator of drilling fluid.

n: see methylorange filtrate alkalinity.

n: see Pm alkalinity.
