KI will crash out completely but KBr and KCl will be partially soluble in THF, particularly KCl. This is due to the THF being polar. For a salt elimination reaction in THF remove the THF and extract with toluene then filter to have the salt completely crash out in the non-polar toluene.
The balanced equation for the reaction is: 2KF + Cl2 -> 2KCl + F2
The double replacement reaction between potassium fluoride and hydrobromic acid would result in the formation of potassium bromide and hydrofluoric acid. The balanced chemical equation for this reaction is: 2KF + 2HBr → 2KBr + 2HF.
KF has small size than KCl. So the packing of atoms / ions in KF is more than that in KCl. So a larger energy is needed to separate the atoms from solid state to liquid state and hence KF has higher melting point than KCl.
These are the ions and their charges: K+1 F-1. The charges have to add up to zero, so one +1 potassium ion already cancels out one -1 fluorine ion. Therefore, the formula is KF.
The kf factor, or soil permeability factor, is a measure of a soil's ability to conduct water. It is used in hydrology and geotechnical engineering to calculate the rate of water flow through soil. A higher kf factor indicates greater permeability and faster water flow.

NO IT WILL NOT DISSOLVE IN ORGANICS Actually, maleic acid [CAS#110-16-7] does have some organic solubility. One can dissolve >100mg per 1mL in isopropanol (IPA) and tetrahydrofuran (THF). Solubility in isopropyl acetate (IPAc) is extremely low. All solvents used in this survey were "anhydrous" (<100 ug/mL H2O by KF). I have not examined other solvents.
The KF is greater than the sum of its partsOwnership of the KF is dispersedPower in the KF flows down…and upThe KF is held together by reputation, not controlThe KF runs on information technologyThe KF is a business
If log(Kf) = 5.167 then Kf = 105.167 = 146,983 (approx).
A very common example of an ionic compound is salt. The sodium (Na) and chlorine (Cl) atoms in it form what is called a crystal lattice. It organises atoms into squares, and then boxes and layers the boxes on one another over and over to make a lattice-like structure.
KCl is an ionic compound. The electronegativity of potassium (K) is approximately 0.82. The electronegativity of chlorine (Cl) is approximately 3.16. The difference between these electronegativities is 2.34. This high electronegativity difference is what makes potassium chloride an ionic compound. If the electronegativity difference of two elements is greater than 1.7, it is considered to be an ionic compound. If the difference is between 0.4 and 1.7, the compound is considered to be polar covalent. If the difference is less than 0.4, the compound is considered to be covalent. If the difference is 0 (i.e. the two elements are the same), then the compound is considered to be pure covalent. KCl is ionic because K's electronegativity is 0.82 and Cl's is 3.16. A compound is ionic when the electronegativity on the Pauling Scale is more than 2.1. The difference 2.34, so it is ionic.
The compound KF is ionically bonded.
