There are several tests for sulfate ion to identify from other anions in qualitative analysis. Some of metal sulfate compounds are soluble in water and some metal sulfates form precipitates. Sulfate compounds of several d block metal cations form colours.
29 Αυγ 2023 · Sulfate ion is a very weak base, while \(\ce{HSO4^{-}}\) is a fairly strong acid, with \(K_a = 0.01\). On the other hand, \(\ce{H2SO4}\) is a very strong acid. Because it is such a weak base, sulfate ion undergoes negligible hydrolysis in aqueous solution.
1 Οκτ 2010 · The pitting corrosion behavior of 13Cr steel was investigated in simulated boiler waters containing chloride ions (Cl-) and sulfate ions (SO42-) using potentiodynamic and potentiostatic ...

Method: Colorimetric, with test strips, 200 - 400 - 800 - 1200 - 1600 mg/L (SO 4 2-), MQuant ® The MQuant ® Sulfate test strips can be used to give a rapid estimation of the sulfate ion content of drinking and industrial water, as well as of effluent discharged, for instance, from electroplating works and leather goods manufacturers. Sulfate ions react with a red thorin-barium complex ...
30 Ιουν 2021 · The early presence of sulfate ions in a saturated calcium hydroxide solution was shown to affect the corrosion behavior of the steel. The higher sulfate ion concentrations resulted in the increase of the anodic current exchange density.
The sulfate ion is a polyatomic anion with the empirical formula S O 42− and a molecular mass of 96.06 daltons; it consists of a central sulfur atom surrounded by four equivalent oxygen atoms in a tetrahedral arrangement.
