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.
Lead tetrachloride can be made by reacting lead(II) chloride PbCl 2, and hydrochloric acid HCl, in the presence of chlorine gas (Cl 2), [5] leading to the formation of chloroplumbic acid H 2 PbCl 6. It is then converted to the ammonium salt (NH 4 ) 2 PbCl 6 by adding ammonium chloride (NH 4 Cl).
A perchlorate is a chemical compound containing the perchlorate ion, ClO − 4, the conjugate base of perchloric acid (ionic perchlorate).As counterions, there can be metal cations, quaternary ammonium cations or other ions, for example, nitronium cation (NO + 2).
Chlorate is the common name of the ClO − 3 anion, whose chlorine atom is in the +5 oxidation state.The term can also refer to chemical compounds containing this anion, with chlorates being the salts of chloric acid.
Lead(II) sulfate is poorly soluble, as can be seen in the following diagram showing addition of SO 2− 4 to a solution containing 0.1 M of Pb 2+. The pH of the solution is 4.5, as above that, Pb 2+ concentration can never reach 0.1 M due to the formation of Pb(OH) 2. Observe that Pb 2+ solubility drops 10,000 fold as SO 2− 4 reaches 0.1 M.
Pb(NO 3) 2 + 2 HCl → PbCl 2 (s) + 2 HNO 3. It also forms by treatment of basic lead(II) compounds such as Lead(II) oxide and lead(II) carbonate. Lead dioxide is reduced by chloride as follows: PbO 2 + 4 HCl → PbCl 2 (s) + Cl 2 + 2 H 2 O. It also formed by the oxidation of lead metal by copper(II) chloride: Pb + CuCl 2 → PbCl 2 + Cu
Chlorine perchlorate is a chemical compound with the formula Cl 2 O 4. This chlorine oxide is an asymmetric oxide, with one chlorine atom in +1 oxidation state and the other +7, with proper formula ClOClO 3. It is produced by the photodimerization of chlorine dioxide (ClO 2) at room temperature by 436 nm ultraviolet light: [2] [3] [4] 2ClO 2 ...
ClO3 may refer to: The chlorate anion, Monochlorine trioxide, a hypothetical radical akin to chlorine dioxide; The empirical formula for dichlorine hexoxide / chloryl perchlorate; The perchloryl cation, +
