(PNNL), Richland, WA (United States) USDOE Office of River Protection (ORP), Richland, WA (United States) From Sciencemadness Wiki navigation search Chromium (III) sulfate is the inorganic compound with chemical formula Cr2(SO4)3.

For example, the hydroxide salt Mg (OH) 2 is relatively insoluble in water: Mg(OH)2 ( s) Mg2 + (aq) + 2OH (aq) with Ksp 5. of Washington, Seattle, WA (United States) In contrast, pH has little to no effect on the solubility of salts whose anion is the conjugate base of a stronger weak acid or a strong acid, respectively (e.g., chlorides, bromides, iodides, and sulfates). (PNNL), Richland, WA (United States) Univ. of Standards and Technology (NIST), Gaithersburg, MD (United States) It is proposed that the negative effect of chlorine and chromium on sulfur solubility can be explained based on the simple hypothesis that sulfur, chlorine, and chromium are present in the glass as anions competing for the voids or interstitial sites of the glass matrix, and that their solubility more » strongly depends on the effective size of corresponding anions. The glass compositions were analyzed by inductively coupled plasma–atomic emission spectroscopy, ion chromatography, and X-ray emission spectroscopy. Three mixing-melting-quenching cycles were applied to determine saturation concentrations of sulfur, chromium, and chlorine incorporated into the simplified LAW glass. A crucible-scale salt-saturation was performed by mixing the crushed glass powder with an excess amount of salts, melting at 1150 ☌ for one hour, and quenching. A simplified LAW glass was prepared and saturated by sodium sulfate, sodium chloride, and sodium chromate salts as single components and as mixtures with different ratios at 25 mol%, 50 mol%, and 75 mol% of sulfate mixed with chloride or chromate. Specifications Solubility Information, Soluble in water. This work was aimed at understanding the mechanism behind the negative effect of chlorine and chromium on sulfur solubility. When we write the two together we get Cr 2 (SO 4 ) 3.According to an empirical sulfur solubility model developed from over 200 simulated low-activity waste (LAW) glasses, chlorine and chromium show strong effects on lowering sulfur solubility in glass. So, to arrive at the formula of Chromium III Sulfate, we will interchange the charges of ions Cr +3and SO 4 -2 to get Cr 2 and (SO 4 ) 3.Cr is placed outside the parentheses as it is not a polyatomic ion. (Cr2(SO4) 3 18 H0), with 99.9 pct purity was procured from J. So, polyatomic ion SO 4 -2 will be placed inside parenthesis. 1) Commercially available, water-soluble violet chromium sulfate. The sulfur and oxygen atoms share a covalent bond.

So, the Charge carried by the chromium cation Cr +3 will be written as the subscript of the sulfate anion SO 4 -2 and the Charge carried by the sulfate anion SO4-2 will be written as subscript for the chromium cation Cr +3.

Chromium III has a valence of 3 and Sulfate has a valence of 2, we will need 2 chromium and 3 sulfate ions to balance 6 valence ties.

It is an ionic compound where Chromium (Cr) is the metal with Cr+3 cation and sulfate is the SO4-2 anion.

Solubility: 250 g/l: Dimensions Materials Information Toxicological Information Safety Information according to GHS Hazard. The chemical analysis data show that the chromium and chlorine incorporated in the glass have strong negative effects on sulfur solubility, which can be qualitatively explained by the sulfur, chlorine, and chromium ions competing for voids in the glass matrix. The formula of Chromium III Sulfate is Cr 2(SO 4) 3.
