| exponent | 1. <mathematics> A number, letter, or any quantity written on the right hand of and above another quantity, and denoting how many times the latter is repeated as a factor to produce the power indicated. Thus a^2 denotes the second power, and a^n the xth power, of a (2 and x being the exponents). A fractional exponent, or index, is used to denote the root of a quantity. Thus, a^1/3 denotes the third or cube root of a. 2. One who, or that which, stands as an index or representative; as, the leader of a party is the exponent of its principles. Exponent of a ratio, the quotient arising when the antecedent is divided by the consequent; thus, 6 is the exponent of the ratio of 30 to 5. Origin: L. Exponens, -entis, p. Pr. Of exponere to put out, set forth, expose. See Expound. Source: Websters Dictionary (01 Mar 1998) |
| colourimetric titration | A titration in which the end point is marked by a colour change. (05 Mar 2000) |
| whole-body titration curve | A graphic representation of the in vivo changes in hydrogen ion, PaCO2, and bicarbonate which occur in arterial blood in response to primary acid-base disturbances. (05 Mar 2000) |
| potentiometric titration | A titration during which the pH is continually measured with some value of the pH serving as end point. (05 Mar 2000) |
| skin test end-point titration | A quantitative form of intradermal testing for the relative allergenicity of a substance. It is used to determine the amount of an allergen that will be tolerated in immunotherapy. (12 Dec 1998) |
| titration | <chemistry> The act or process of titrating; a substance obtained by titrating. Source: Websters Dictionary (01 Mar 1998) |
| formol titration | A method of titrating the amino groups of amino acids, by adding formaldehyde to the neutral solution; the formaldehyde reacts with the NH3+ group, liberating an equivalent quantity of H+, which may then be estimated by titration with NaOH. (05 Mar 2000) |
