Lead perchlorate trihydrate is produced by the reaction of lead(II) oxide, lead carbonate, or lead nitrate by perchloric acid: . Pb(NO 3) 2 + HClO 4 → Pb(ClO 4) 2 + HNO 3. The excess perchloric acid was removed by first heating the solution to 125 °C, then heating it under moist air at 160 °C to remove the perchloric acid by converting the acid to the dihydrate.
Although thermodynamically a mild reductant, Fe 2+ ion exhibits a stronger trend to remain coordinated by water molecules to form the corresponding hexa-aquo complex in solution. The high activation energy of the cation binding with perchlorate to form a transient inner sphere complex more favourable to electron transfer considerably hinders ...
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.
It dissolves in nitric acid with the evolution of nitric oxide gas to form dissolved Pb(NO 3) 2. [8] It is a well-soluble solid in water; it is thus a key to receive the precipitates of halide, sulfate, chromate, carbonate, and basic carbonate Pb 3 (OH) 2 (CO 3) 2 salts of lead. [3]
The chlorate ion cannot be satisfactorily represented by just one Lewis structure, since all the Cl–O bonds are the same length (1.49 Å in potassium chlorate [1]), and the chlorine atom is hypervalent. Instead, it is often thought of as a hybrid of multiple resonance structures:
It is about ten times more soluble in boiling water. [5] PbBr 2 has the same crystal structure as lead chloride – they are isomorphous. In this structure, Pb 2+ is surrounded by nine Br − ions in a distorted tricapped trigonal prismatic geometry. Seven of the Pb-Br distances are shorter, in the range 2.9-3.3 Å, while two of them are longer ...
Addition of chloride ions to a suspension of PbCl 2 gives rise to soluble complex ions. In these reactions the additional chloride (or other ligands) break up the chloride bridges that comprise the polymeric framework of solid PbCl 2(s). PbCl 2(s) + Cl − → [PbCl 3] − (aq) PbCl 2(s) + 2 Cl − → [PbCl 4] 2− (aq) PbCl 2 reacts with ...
It forms white crystals, which are sparingly soluble in cold water and ethanol. It dissolves more easily in hot water. It dissolves more easily in hot water. CsClO 4 is the second least soluble of the alkali metal perchlorates (after Fr, followed by Rb, K, Li, and Na), a property which may be used for separatory purposes and even for ...
