Etymology: < titrate v. + -ed suffix¹, after French titré (1851 or earlier).

1. Chemistry. That has undergone titration; measured by means of titration.In early use perhaps: of known concentration.

1860 Q. Jrnl. Chem. Soc. 12 40 The distillate may be caught in a titrated acid solution, and the quantity of ammonia formed estimated, from which the nitric acid present may be calculated.

1863 Intellectual Observer July 457 Titrated solutions are thus named from the French, and signify their having a definite strength, or power, so that the action of precipitation or otherwise exerted by a given quantity is readily capable of arithmetical expression, and thus indicates the quantity of the substance acted upon.

1881 Nature 6 Oct. 552/1 Determination of phosphoric acid by titrated liquors, by M. Perrot.

1946 F. Schneider Qualitative Org. Microanalysis vi. 163 For the identification of the acid portion of the ester use the titrated solution from the determination of the saponification equivalent.

1954 Mechanization Mar. 96/2 The titrated acidity of each sample remained constant for the entire period.

2011 G. E. Rayment & D. J. Lyons Soil Chem. Methods xv. 347 Add a known volume (5–10 mL) of 0.02 M NH₄Cl to the titrated liquid.

2. Medicine. Of the dosage of a drug or other treatment: adjusted by incremental changes to achieve a desired response or outcome (cf. titrate v. 2). Also in extended use and figurative: adjusted or controlled carefully.
