Lead salts must be absent in the titration, and so must strontia and lime.
The acid numbers, determined by titration in the usual way, are 10-20 p.ct.
The titration of the zinc takes less time, and, with ordinary working, is more trustworthy than the gravimetric method.
This may be done by titration in alcohol which has been neutralized.
But if the starch is added before the titration, the results are liable to error.
Or the milk sugar may be determined by titration with a standard copper solution.
The solution is then ready for titration with the standard permanganate solution.
The absorption flask is then disconnected and the amount of absorbed carbon dioxide estimated by titration.
Fleury has proposed a titration by oxalic acid as follows:—2 grms.
From this titration the amount of acid to be added is again calculated and more acid is added if necessary.
1864, from French titrer, from titre "standard, title" (see title (n.)), also "fineness of alloyed gold;" in chemistry, the establishment of a standard strength or degree of concentration of a solution.
titration ti·tra·tion (tī-trā'shən)
The process, operation, or method of determining the concentration of a substance in a solution to which the addition of a reagent having a known concentration is made 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.
titrate ti·trate (tī'trāt')
v. ti·trat·ed, ti·trat·ing, ti·trates
To determine the concentration of a solution by titration or perform the operation of titration.
The process or operation of determining the concentration of a substance in solution. Titration is performed by adding to a known volume of the solution 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.
Note: The term titration is occasionally used informally to suggest extreme precision in some sort of measurement or determination.
