Can AlF3 dissolve in ~40% HF with the present of KF, or can the reaction just happen in pure HF? Want to find a easy way to digest the silicate, which is rich of aluminium. Inorganic Chemistry HF/KF (pKa = 3.14) HNO2/KNO2 (pKa = 3.39) NH3/NH4Cl (pKa = 9.25) HClO/KClO (pKa = 7.46) b) for the best buffer system, calculate the ratio of the molarities of the buffer components required to 02/05/40 · Intel has officially launched the F-series and KF-series desktop processors. The difference between these and their respective non-K counterparts is the lack of an integrated GPU or iGPU. Time will tell however if the iGPU is physically removed or just disabled. Clock speeds, cache, and TDP are identical between the F-series and standard K KF Valves manufactures a broad range of flow control products for the oil and gas production, pipeline, petrochemical, and industrial markets. KF Valves provides the broadest range of flow control products in the industry for the oil and gas production, pipeline, petrochemical and industrial markets. The company’s proven flow control products I guess a probable answer for the cause of insolubility could be: "the nonavailability of $\ce{F-}$ ions because of the presence of intermolecular hydrogen bonding in $\ce{HF}$, which makes $\ce{AlF3}$ insoluble in $\ce{HF}$." Can someone elaborate the cause and mention other such reagents like $\ce{KF}$ which can be used for the same purpose? Hydrogen fluoride react with potassium hydroxide to produce potassium fluoride water. HF + KOH → KF + H 2 O [ Check the balance ] Hydrogen fluoride react with potassium hydroxide to produce potassium fluoride water. Hydrogen fluoride and potassium hydroxide - diluted solutions. Сoding to search: HF + KOH = KF + H2O. Add / Edited: 07 Calculate the ph of a buffer consisting of 0.50 m hf and 0.45 m kf (a) before and (b) after addition of 0.40 g of naoh to 1.0 l of the buffer (ka of hf = - 9640959

A strong electrolyte (strong acid or strong base) will be more conductive than a weak electrolyte (weak acid or weak base), so you are simply comparing the acidic/basic properties of KF and HF. HF is a weak acid mostly due to the strong attraction between hydrogen and fluorine ions. KF will form potassium and fluorine ions in solution.

Potassium fluoride is the chemical compound with the formula KF. After hydrogen fluoride, KF is K2CO3 + 4HF → 2KHF2 + CO2↑ + H2O: KHF2 → KF + HF↑. Platinum or heat resistant plastic containers are often used for these operations.
