Today, I am going to show you how to perform the titration of the ascorbic acid
by an iodine titrated solution
First, in this beaker
I have prepared 44 mg of ascorbic acid
as a test sample in order to get a theoretical endpoint
of 5 ml of iodine
The ascorbic acid is dissolvable in water
so the first step is to solubilize it
This titration needs to take place in acid media
so I add 5 ml of diluted sulfuric acid R
Therefore, be careful
because you will manipulate concentrated acid
In order to get a homogeneous titration
I add a stirring bar in the beaker
The reactants are now ready
the titration can be started
