Does kf is molecular or ionic?

Krypton difluoride (KF) is an ionic compound composed of krypton and fluorine ions. The electronegativity difference between krypton and fluorine causes the transfer of electrons, leading to the formation of ionic bonds in KF.


In a reaction the equilibrium constant for the forward reaction is Kf and the equilibrium constant of the backward reaction is KB What is the relationship between Kf and KB?

The relationship between Kf and KB is that they are reciprocals of each other. Mathematically, Kf = 1/KB. This means that if Kf is large, then KB will be small and vice versa.


How can the Kf value of a solvent can be determined?

The Kf value of a solvent can be determined experimentally by measuring its freezing point depression when a known amount of solute is added. The formula used is ΔTf = Kf * m, where ΔTf is the depression in freezing point, Kf is the cryoscopic constant for the solvent, and m is the molality of the solution. By rearranging this formula, Kf can be calculated by Kf = ΔTf / m.


What is the molarity of a kf(aq) solution containing 116grams of kf in 1.00 liter solution?

The molar mass of KF is 58.1 g/mol. Given that there are 116 grams of KF in the solution, this corresponds to 2 moles of KF. Therefore, the molarity of the solution is 2 M.


In BrF3 as a solvent SnF4 and KF behave as?

well BrF3 will auto dissociate to give BrF4- + BrF2+ ...the KF will give a F- to the BrF3 obviously this giving is really due the higher electronegativity of the fluorine thus their will be an increase in the amounts of BrF4- in solution .Using the solvent-system definition of an acid or base.Any specie (molecule ,ion)which increases the anionic or negatively charged amounts of species in solution is a base.So KF definitely behaves as a base. You can use this same reasoning for SnF4 and try and figure that one out on your own.good luck .
