(a)
refers to that group of analytical techniques which takes advantage of titers or concentrations of solutions
(a)
In ( (a) ) the word "titer" refers to the fineness of gold or silver
In ( (a) ) it is the measure of the concentration of a solution;
In ( (a) ) it is defined as the extent to which an antibody solution can be diluted before it ceases to give a positive reaction with an antigen
In ( (a) ) we add a reagent, called the titrant, to a solution containing another reagent, called the titrand, and allow them to react
It is used rather to denote a quantity of some other measurement parameter which relates directly to the quantity of analyte which is to be measured
(a)
It establishes a quantity of analyte using volumes of reagents of known concentrations and the knowledge of the stoichiometry of the reactions between the reagents and the analyte
(a)
It determines the quantity of analyte by a measure of the mass of a solution of known concentration
(a)
arrives at the amount of analyte by measuring the duration of a given electrical current
(a)
in which an acidic or basic titrant reacts with a titrand that is a base or an acid;
(a)
based on metal–ligand complexation;
(a)
in which the titrant is an oxidizing or reducing agent
(a)
in which the titrand and titrant form a precipitate.
(a)
at which some detection technique tells you that chemical equivalence has been reached.
(a)
A ( (a) ) is a long, narrow tube with graduated markings, equipped with a stopcock for dispensing the titrant.
