Why is titration used when standardizing a solution?

I posted this answer to Titration is a cost effective and an easy analytic method to deduce the exact concentration of a solution. Titration is easiest of all the analytic methods available to find out the exact concentration of a solution. It is quite simple as all we need is a burette, a pipette, and a suitable indicator, in case the end point is … Continue reading Why is titration used when standardizing a solution?
