Lead(II) fluoride can be prepared by treating lead(II) hydroxide or lead(II) carbonate with hydrofluoric acid: [3]. Pb(OH) 2 + 2 HF → PbF 2 + 2 H 2 O Alternatively, it is precipitated by adding hydrofluoric acid to a lead(II) salt solution, or by adding a fluoride salt to a lead salt, such as potassium fluoride to a lead(II) nitrate solution, [4]
Potassium hexafluoronickelate(IV) is an inorganic compound with the chemical formula K 2 NiF 6. It can be produced through the reaction of potassium fluoride, nickel dichloride, and fluorine. It reacts violently with water, releasing oxygen. It dissolves in anhydrous hydrogen fluoride to produce a light-red solution.
Oxygen difluoride was first reported in 1929; it was obtained by the electrolysis of molten potassium fluoride and hydrofluoric acid containing small quantities of water. [7] [8] The modern preparation entails the reaction of fluorine with a dilute aqueous solution of sodium hydroxide, with sodium fluoride as a side-product:
The mass ratio of the solvent and potassium fluoride is 1.1~2.0 : 0.5~1. When the reaction temperature of 100~160 °C is reached, methyl chloroacetate ClCH 2 CO 2 CH 3 is continuously added in the reactor at a speed of 5~10 kg/min with the mass ratio of methyl chloroacetate and potassium fluoride being 1:0.5～1. The reaction between these ...
Potassium bifluoride is the inorganic compound with the formula K[HF 2]. This colourless salt consists of the potassium cation (K +) and the bifluoride anion ([HF 2] −). The salt is used as an etchant for glass. Sodium bifluoride is related and is also of commercial use as an etchant as well as in cleaning products. [3]
