WebJan 13, 2024 · Complexometric titration or chelatometry, on the other hand, is a method of analytical chemistry. It is primarily used for the quantitative determination of metal in an aqueous solution. In order to use this to calculate the titration, an indicator is used which is optically different in the free state from the form bound to metals. WebThe acid-base properties of Solochrome Black P.V. have been studied with the object of applying it as a metallochromic or as a chromophoric indicator. The pK values of 4.1, 7.0 and ∼ 11 corresponding to the three steps of ionisation of the free acid were evaluated by aid of the relation between log (acid)/(salt) and pH values obtained during the course of …
