In strongly acidic media (pH 1.0–1.5), the reduction reaction rate decreases due to the instability of the thiosulfate ion. At pH 3.5, the iron(III) thiocyanate complex is destroyed, and iron is precipitated in the form of hydroxide.

Thiosulfate (IUPAC-recommended spelling; sometimes thiosulphate in British English) is an oxyanion of sulfur with the chemical formula S2O2−3. Thiosulfate also refers to the compounds containing this anion, which are the salts of thiosulfuric acid, e.g. sodium thiosulfate Na2S2O3. Thiosulfate also refers to the esters of thiosulfuric acid, e.g. O,S-dimethyl thiosulfate CH3−O−S(=O)2−S−CH3… WebApr 12, 2024 · The effect of thiosulfate (S 2 O 3 2− ) with the different concentrations (100 g m −3 , 150 g m −3 , 200 g m −3 ) on the passivation of Zn alloys in artificial seawater at 353 K is investigated by using immersion tests, electrochemical measurements, and field emission scanning electron microscopy (FE-SEM) with EDX. orc in wow https://nt-guru.com
