Method Of Titration

There are many instances in today’s society and on this planet, where it is crucial to figure out the unknown concentration of a known substance. The process that is used to figure out the unknown concentration of a substance is the process known as titration. Titrations are used in a wide range of work environments including forensic labs, and pharmaceuticals. A way in which titrations could aide society could start in a forensic lab. It could be used when trying to figure out the concentration of a drug or poison that may have been used in a crime. In a pharmaceutical environment it could be used to properly give out the dosages to patients that require medicine. The method of titration can be defined as the discovery of a concentration of …show more content…
