Ion A. Atanasiu (25 September 1894 – 19 December 1978) was the founder of the Romanian School of Electrochemistry and the first to teach this subject in Romania. He is known as the originator of cerimetry , an analytical method based on Cerium (IV) as titration reagent .
Cerimetry or cerimetric titration, also known as cerate oximetry, is a method of volumetric chemical analysis developed by Ion Atanasiu. It is a redox titration in which an iron(II)–1,10-phenanthroline complex color change indicates the end point. Ferroin can be reversibly discolored in its oxidized form upon titration with a Ce 4+ solution ...
Ion concentration can change significantly in a titration, which changes the conductivity. (For instance, during an acid–base titration, the H + and OH − ions react to form neutral H 2 O.) As total conductance depends on all ions present in the solution and not all ions contribute equally (due to mobility and ionic strength ), predicting ...

For a strong acid-strong base titration monitored by pH, we have at any i'th point in the titration = [+] [] where K w is the water autoprotolysis constant.. If titrating an acid of initial volume and concentration [+] with base of concentration [], then at any i'th point in the titration with titrant volume ,
Note that iodometry involves indirect titration of iodine liberated by reaction with the analyte, whereas iodimetry involves direct titration using iodine as the titrant. Redox titration using sodium thiosulphate, Na 2 S 2 O 3 (usually) as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The ...
A chloridometer is a measuring instrument used to determine the concentration of chloride ions (Cl –) in a solution.It uses a process known as coulometric titration or amperostatic coulometry, the accepted electrochemistry reference method to determine the concentration of chloride in biological fluids, including blood serum, blood plasma, urine, sweat, and cerebrospinal fluid.
The key to determine the amount of each acid present in the mixture is the ability to obtain an accurate value for the amount of phosphoric acid present, as revealed by titration of the third proton of H 3 PO 4. Figure 10 illustrates a titration plot of this mixture, showing 3 sharp endpoints. Fig. 11. Titration plots for determination of ...
