Iron chromate solubility
WebIt is slightly soluble in water (with solubility product K sp = 2.36×10 −6 at 25 °C) [13] as well as dilute hydrofluoric acid, giving a pale green solution. [1] It is insoluble in organic solvents. [5] The tetrahydrate can be prepared by dissolving iron in warm hydrated hydrofluoric acid and precipitating the result by addition of ethanol. [1] WebThe solubility of CaF 2 (molar mass 78.1) at 18°C is reported to be 1.6 mg per 100 mL of water. Calculate the value of Ks under these conditions. Solution moles of solute in 100 mL; S = 0.0016 g / 78.1 g/mol = 2.05 × 10 − 5 mol S = 2.05 × 10 – 5mol 0.100L = 2.05 × 10 − 4M Ksp = [Ca2 +][F –]2 = (S)(2S)2 = 4 × (2.05 × 10 – 4)3 = 3.44 × 10 – 11

WebAug 21, 2024 · The chromate (VI)-dichromate (VI) equilibrium You are probably more familiar with the orange dichromate (VI) ion, Cr 2 O 7 2 −, than the yellow chromate (VI) ion, CrO 4 2 −. Changing between them is easy; i f dilute sulfuric acid is added to the yellow solution it turns orange. WebFor ionic compounds with limited solubility in water, an equilibrium constant, Ksp, can be defined from the ion concentration in water from the equation: MmAn(s) = mMn+(aq) + nAm-(aq) where M m A n is the slightly soluble substance and M n+ and A m- are the ions produced in solution by dissosiation of M m A n. Ksp = [Mn+]m * [Am-]n
