TITRATIONS

In volumetric analysis, the process of determination of strength of an unknown solution by another solution of known strength under volumetric conditions is known as titration. Titrations are of various types-The fundamental basis of all titration is the law of equivalence which -states that at the end point, the milliequivalent of known solution is equal to milliequivalent of given unknown solution which is observed by using an indicator.



Simple Titration

In a simple titration, a solution of substance A of unknown concentration is made to react with a solution of reagent 8 whose concentration is known, so that the concentration of A may be calculated.

N₁V₁ = N₂V₂ = N₂= ((N₁ V₁)/V₂ )

 

   Back Titration

Let us assume that we have a solid C which is impure and we want to calculate the percentage purity. We are given two reagents A and B, where the concentration of A is unknown while that of B is known (N₁).

Note: (i) A, B and C should be such that A reacts with B, A reacts with C and the product of A and C cannot react with B.

(ii) Gram equivalent of A should be either greater than or equal to gram equivalents of C. meq. of C = (meq. of A - meq. of B)
