Student: titration trial essay example abstract the concentration of an unknown can be easily found by a scientific method called titration ethylene-diaminetetraacetate commonly known as edta is a complexing agent used to measure metal ions by titration.
A redox titration, involving an iodometric method, will be used to do the analysis the samples will be classified by their vitamin c content introduction: although most mammals can synthesize vitamin c, or ascorbic acid (c6h8o6), from sugars, man must ingest considerable quantities of this substance. Discussion: a redox titration involves a reducing agent and an oxidizing agent in this experiment, ammonium iron (ii) sulphate was the reducing agent and potassium manganate was the oxidizing agent. The redox reaction is preferable to an acid-base titration because a number of other species in juice can act as acids, but relatively few interfere with the oxidation of ascorbic acid by iodine this method determines the vitamin c concentration in a solution by a redox titration with potassium iodate in the presence of potassium iodide.
