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.
30 Ιουν 2021 · The role of sulfate ions on corrosion of steel in alkaline solutions (including cementitious materials) has been contested in the literature due to the effects of the many exposures, material and test conditions.
1 Ιουν 2022 · The behavior of galvanized steel exposed to strong alkaline solutions (pH values of 12.7) with a fixed concentration of sulfate ions of 0.04 M is studied here.
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 role of sulfate (SO42-) ions on pitting corrosion of Stainless Steel-316 (SS-316) and inhibition mechanisms of meta-silicate ions (SiO32-) above critical pitting temperature (CPT) were ...
The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO2− 4. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid.
1 Φεβ 2020 · The adsorption of gypsum formed by the reaction of sulfate ions and calcium hydroxide on the steel surface alleviates the steel corrosion. However, the preferred binding of SO 4 2- on the LDHs increases the amount of Cl − in the solution, which leads to the increase of steel corrosion.
