Iron 3 thiosulfate

WebAs my understanding, there should be an oxidation-reduction reaction: 2 F e X 3 + + C u 2 F e X 2 + + C u X 2 +. However, I always see the process using F e C l X 3 to etch copper, but I never see people using F e X 2 ( S O X 4) X 3 to do this. Is it because such reaction does not occur, or is it because F e C l X 3 is acidic in aqueous ...

WebOne of the most common titrations is an acid-base neutralisation, where the concentration of one of the reactants is determined via titration. In the experiment below, methyl orange is used to identify the endpoint of the titration, but some other titrations will use phenolphthalein. The video below outlines the titration procedure. WebThe reaction between iodine and the thiosulfate ion is: I2 + 2S2O2 − 3 ⇌ 2I − + S4O2 − 6 This reaction proceeds quantitatively in neutral or slightly acidic solutions. In strongly alkaline or acidic solutions the oxidation of the thiosulfate does not proceed by a single reaction.
