What is a titration?

Titration: is a very useful technique to determine the concentration of an unknown. In most experiments, this ascertained by measuring the PH of the solution. However, often scientist add an indicator to the solution to find out the concentration of unknown. The indicator will change the colour of the solution to give an assessable endpoint to the reaction. The skills that I have developed during the titration experiment will definitely help me in my future studies, as I would like to continue my higher education in science-related subjects. Titration use in pharmacy to analyse the quantitative measurement or ingredient of the drugs. Titration provides standard methods for the essay of unformulated drugs. Moreover, it is used for standardisation of raw materials and inter intermediates used in drug synthesis. On the other hand, titration is used to determine the concentration of alcohol in the blood and urine which can be very useful for a forensic science investigation.

The other usage of titration is to determine the concentration of vitamin C in drugs. Scientists do this by adding the blue dye Dichlorophenolindophenol. The reaction between the indicator and the vitamin C leads to the colour change, and the colour will change to colourless. This is very useful to make different concentration vitamin C drugs according to customer needs.

Diabetes is one of a condition which the amount of glucose in the blood goes higher than the normal level. By using the titration method, we can determine the amount of glucose in urine. In this technique glucose reduce cupric ions which react with potassium thiocyanate to produce a white precipitate, indicating endpoint.
