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.
Tripotassium phosphate, also called tribasic potassium phosphate [3] is a water-soluble salt with the chemical formula K 3 PO 4. (H 2 O) x (x = 0, 3, 7, 9). [ 4 ] Tripotassium phosphate is basic: a 1% aqueous solution has a pH of 11.8.
It often occurs as the trihydrate K 3 [Fe(C 2 O 4) 3]·3H 2 O. Both are crystalline compounds, lime green in colour. [4] The compound is a salt consisting of ferrioxalate anions, [Fe(C 2 O 4) 3] 3−, and potassium cations K +. The anion is a transition metal oxalate complex consisting of an iron atom in the +3 oxidation state and three ...
A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule. For example, boron trifluoride (BF 3) has a trigonal planar arrangement of three polar bonds at 120°. This results in no overall dipole ...
Both are yellow, water-soluble, diamagnetic solids. The salt consists of potassium ions and the tetracyanonickelate coordination complex, which is square planar. The [Ni(CN) 4 ] 2- anions are arranged in a columnar structure with Ni---Ni distances of 4.294 Å, which is well beyond the sum of the van der Waals radius of the nickel cation. [ 1 ]
Krogmann's salt is a series of partially oxidized tetracyanoplatinate complexes linked by the platinum-platinum bonds on the top and bottom faces of the planar [Pt(CN) 4] n− anions. This salt forms infinite stacks in the solid state based on the overlap of the d z2 orbitals. [2]
2 K 4 [Fe(CN) 6] + Cl 2 → 2 K 3 [Fe(CN) 6] + 2 KCl. This reaction can be used to remove potassium hexacyanidoferrate(II) from a solution. [citation needed] A famous reaction involves treatment with ferric salts, most commonly Iron(III) chloride, to give Prussian blue. In the reaction with Iron(III) chloride, producing Potassium chloride as a ...
Menadiol is an organic compound with the formula C 6 H 4 (COH) 2 (CH)(CH 3). It is formally a derivative of p-hydroquinone. The name vitamin K 4 can refer to: specifically this compound, [1] [2] its various esters, e.g. menadiol diacetate (acetomenaphthone), [3] [4] menadiol dibutyrate, [4] menadiol dimalonate, or [2] its various salts, like
