EBT forms an unstable wine-red colored complex with Ca2+/Mg2+ions, which upon titrating with EDTA, results in the breaking of EBT-Ca2+/Mg2+ unstable bond and formation of …
WebFeb 23, 2016 · 2. The two pKa values for carbonic acid are given as 6.37 and 10.25, so you may want to pick the midpoint between these (pH 8.31) as your equivalence point. At that pH, a tiny amount of base will change the pH a lot, so the amount of base needed should not depend strongly on the exact value you select for the equivalence point.
Webrange. As titration is an absolute method, the linearity can usually be obtained directly. For this, at least five different concentrations are titrated and a linear regression of the sample size versus the consumed titration volume is established.
