Double titration means two titrations are done in a process. In this process:The first titration is done to standardize the titrant (usually taken in burette).The second titration is used to find the molarity of the titrand (unknown solution and taken in conical flask).For example, we have to calculate molarity of HCl acid by titrating it with NaOH base. But for that NaOH must also be standardized.So for the whole process, we do double titration. First we standardize NaOH by titrating it with a standard oxalic acid solution. And then, we find out the molarity of HCl by titrating it with standardized NaOH solution. Here we know the normality of oxalic acid so from first titration observation we find the normality of NaOH using N¹V¹ = N²V². Now knowing the value of N² we do the 2nd titration which gives us the value V³ and again by using N²V² = N³V³ we find N³. This is the calculation process for double titration ................Yugal Kishore Sahu
