Titration – Exam Practice

Titration – Exam Practice

Titration is an essential technique used in many areas of chemistry to determine the concentration of a solution. In this practical experiment, the aim is to determine the value of x in Fe(NH4)2(SO4)2.xH2O using titration against a standard solution of potassium manganate (VII). The obtained results are used to calculate the amount of water of crystallization in the salt. This blog post provides an overview of titration and its importance in chemistry, as well as a step-by-step procedure and calculations for the Fe(NH4)2(SO4)2.xH2O experiment.
