These chains then pack hexagonally with adjacent chains offset by +/- 1/3 of the c lattice parameter. This is the same as the structure adopted by the high temperature polymorph of copper(I) cyanide. The silver to carbon and silver to nitrogen bond lengths in AgCN are both ~2.06 Å [4] and the cyanide groups show head-to-tail disorder. [5]
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
1.03·10 −12 [2] Solubility: Insoluble in acids (reacts) [3] except when concentrated, acetates, aq. nitrates [1] Solubility in silver nitrate: 43.2 mg/L (25.2 °C, 3 n AgNO 3 /H 2 O) [1] Solubility in sulfur dioxide: 14 mg/kg (0 °C) [4] Solubility in methanol: 0.0022 mg/kg [4]
[1] It can be used in silver plating, as a bactericide, and in the manufacture of antiseptics. [2] It forms a variety of coordination polymers, a property that exploits the bridging tendency of the cyanide ligand. [3]
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
It is suspected that this reaction is one step in the conversion of calcium carbide with nitrogen gas. The ratio of calcium cyanide to calcium cyanamide is sensitive to the presence of alkali metal halides, such as sodium chloride. Calcium cyanide hydrolyzes upon acidification to form hydrogen cyanide: Ca(CN) 2 + 2 H + → Ca 2+ + 2 HCN
We have calculated the solubility of AgCl in pure water to be 1.0 x 10 −5 M, if we compare this value to that obtained in presence of diverse ions we see % increase in solubility = {(1.3 x 10 −5 – 1.0 x 10 −5) / 1.0 x 10 −5} x 100 = 30% Therefore, once again we have an evidence for an increase in dissociation or a shift of equilibrium ...
