Potassium fluoride (KF) is soluble in HF. Join Yahoo Answers and get 100 points today. For the salts having large anions (SO 42-, F, NO3 - HCO3 -, CO3 2-, etc) as ra >>r,, the radii of the cation has little contribution in the total (r + ra) and decreases sharply as we move down the group. Click here 👆 to get an answer to your question ️ What is the solubility order of alkali metal flouride in water? Chemistry General Chemistry - Standalone book (MindTap Course List) Explain the trends in solubility (grams per 100 mL of water) of the alkali-metal fluorides and permanganates. Fluorides of alkali metals, ammonium, aluminium, tin and mercury are soluble in water. Thus, in these salts, the decrease in lattice energy is greater than the decrease in Li+ Na+ K+ Rb+ Cs+ F- 0.27 4.2 92 131 367 MnO­4- 71 Very Soluble 6.4 0.5 0.097 It Has To Do With Hydration And Lattice Energy, But I Need A Better Explanation.
