The determination of the concentration of some substance in a solution by slowly adding measured amounts of some other substance (normally using a burette) until a reaction is shown to be complete, for instance by the colour change of an indicator
A method of testing by adding a reagent of known strength to a water sample until a specific color change indicates the completion of the reaction
a measured amount of a solution of unknown concentration is added to a known volume of a second solution until the reaction between them is just complete; the concentration of the unknown solution (the titer) can them be calculated
progressive, stepwise increase in CPAP pressure applied during a polysomnogram to establish the optimal treatment pressure
a method of analyzing the composition of a solution by adding known amounts of a standardized solution until a given reaction (color change, precipitation, or conductivity change) is produced
An analytical method for determining concentration of a desired substance in solution
the measurement of volume; often used to refer to the determination of a drug dosage
procedure for determining the amount of substance A by adding a carefully measured volume of a solution of known concentration of B until the reaction of A and B is just complete
The process of finding the quantity of a given chemical or substance by the addition of a liquid reagent of known strength, and measuring the volume of that reagent necessary to cause a reaction that changes the form of the chemical in question Transparency The depth to which light will penetrate a body of water Turbid Not clear, or transparent due to stirred up sediment
The process, operation, or method of determining the concentration of a substance in solution by adding to it a standard reagent of known concentration in carefully measured amounts until a reaction of definite and known proportion is completed, as shown by a color change or by electrical measurement, and then calculating the unknown concentration
The process of determining the concentration of a dissolved substance in terms of the smallest amount of reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution
{i} addition of solution of known concentration to solution of unknown concentration (Chemistry)
The measurement of the volume of a solution of known concentration required to react completely with an unknown quantity of another substance
The adjustment of a medication's dosage in order to obtain the most favorable clinical response
A method of testing water The end point of the titration process is determined by a pH change, caused by the titration solution being added to the test sample The changing pH triggers the reagent to change colors
Reacting a solution of unknown concentration with a solution of a known concentration for the purpose of finding out more about the unknown solution Back to top V
An analytical process in which a standard solution in a calibrated vessel is added to a measured volume of sample until an endpoint, such as a color change, is reached From the volume of the sample and the volume of standard solution used, the concentration of a specific material may be calculated
adjustment of dosage to obtain best serum level to get efficacy (seizure control) with the least side effects
A Procedure in which one solution is added to another solution until the chemical reaction between the two solutes is complete; the concentration of one solution is known and that of the other is unknown
The process by which the quantity of analyte in a solution is determined from the amount of a standard reagent it consumes Ordinarily, a titration is performed by the careful addition of a known amount of a chemical solution of known strength (titrant) to the completion of the reaction indicated by the end point The volume of standard reagent is then measured
Process of chemical analysis in which the quantity of some constituent of a dissolved sample is determined by adding an exactly measured quantity of another dissolved substance with which it reacts in a definite, known proportion. The solution of known concentration is gradually added to the unknown solution from a burette (a long measuring tube with a valve at the bottom) until the equivalence point (end point) is reached. The amount of the unknown substance can then be calculated. The equivalence point is determined by a detectable change, for instance, of colour in an indicator substance (e.g., litmus) or in an electrical property. Reactions used in titration include acid-base reactions, precipitations (see solution), formation of complexes, and oxidation-reduction reactions. See also pH
To ascertain the amount of a constituent in a solution (or other mixture) by measuring the volume of a known concentration (the "standard solution") needed to complete a reaction
