"Titration" or "titrated" in chemistry, refers to adding one chemical to another, a little bit at a time, to get the two chemicals to provide a certain reaction.
"Titration" or "titrated" is used medically to figure out drug dosages in at least two ways.
1.) It may be to take as little of a drug as possible to get the desired effect. For example, the doctor may start you on 10 mg, and if that is ineffective, gradually increasing the dose to get the maximum effect with the least amount of the medication.
OR
2.) Often used in treatments such as chemotherapy, this method is where you gradually add the drug/treatment dose until the side effects outweigh the benefit of the drug, which is normally only done in the early stages of clinical trials.

there are many uses of titration..to know the volume of one drop of a liquid..
by carrying out a tritation and using your readings in calculations to determine the molarity of the acid against what you are reacting with it. you should find that 1 mol of H2SO4 relaeses 2 moles of hydrogen ions
Both indicators may be used, for example if you have no other kind in the lab. Murexide is used normally as its blue/purple end point for the tritation is more easily observed. Also less murexide is needed for titrations, this is a good thing since indicators by and large are weak acids or bases themselves, thus mimising the impact on the titration figures.
