Abstract niet beschikbaar
The possibility to determine the strength of a sodiumthiosulphate solution (0.1 mol/l) and a potassium bromate-potassium bromide solution (0.017 mol/l) using an automatic titrator has been investigated. The equivalence point of the redox titrations has been visually as well as automatically determined. The redox potential has been measured using a platinum electrode with a silver/ silverchloride reference electrode. The results of the automatic titrations of sodiumthiosulphate solutions do not differ statistically from the results obtained with the manual titration according to the procedure described in NEN 3103. The results of the automatic titrations of potassiumbromate-potassiumbromide solutions do not differ statistically from the results obtained with the manual titration according to the procedure described in the standard operating procedure SOP LAC / 006.
