chemistry specialized（化学）滴定 a method or the activity of finding exactly how much of a substance there is in a solution by gradually adding measured amounts of another substance that reacts to it in a known way, for example by causing a colour change
The acid content of the gastric juice was determined by titration to pH 7.4 with NaOH.
We described above the titration procedure for determining the amount of acid required to neutralize an alkali.
In the practical session we tackled about ten titrations each in three hours.
