Calcium fluoride - Wikipedia
Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF 2. It is a white solid that is practically insoluble in water. It occurs as the mineral fluorite (also called fluorspar), which is often deeply coloured owing to impurities. The compound crystallizes in a cubic motif called the fluorite structure.

2013年3月9日 · CaFX2 C a F X 2 is insoluble in water, but CaClX2 C a C l X 2, CaBrX2 C a B r X 2, CaIX2 C a I X 2 are soluble. Why is this so? Many factors contribute to the solubility of a compound in water. In this case, the main difference between the compounds is …
Calcium Fluoride - an overview | ScienceDirect Topics
It is moderately soluble in water at 142 g/100 ml of water. CaBr 2 ·2H 2 O has a melting point of 38 °C where it dissolves in its own waters of hydration. Its density is 2.290 g/cm 3 .
CaF2 Solubility - Is Calcium fluoride Soluble?
CaF2 is insoluble in water. See the table below to see the exact solubility. You could also determine that CaF2 is insoluble using the rule that fluorides are frequently insoluble.

2022年10月16日 · Calcium fluoride can be prepared by reacting a fluoride, such as sodium fluoride with a soluble calcium salt, such as calcium chloride. Calcium fluoride precipitates out of the solution, which is filtered and dried. Calcium fluoride has poor solubility in water.
At 310 K, the solubility of CaF2 in water is 2.34 × 10 3g/100 mL.
The solubility of C a F 2 is 2 × 10 − 4 mole/litre. Its solubility product is:
Calcium fluoride, solubility - Big Chemical Encyclopedia
The maximum concentration of a salt in an aqueous solution is called the solubility of the salt in water. Solubilities can be expressed in moles of solute per liter of solution (mol/L or M). For example, the solubility of calcium fluoride in water is 3.4 x 10 " mol/L.

2013年7月24日 · Illustration showing the solubility of CaF 2 as a function of pH, represented by the solid blue curve. The predominate form of fluoride in solution is shown by the ladder diagram along the x -axis, with the black rectangle showing the region where both HF and F – are important species.
Calcium Fluoride | CaF2 | CID 84512 - PubChem
CALCIUM FLUORIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic.
• Factors Affecting Solubility o The Common-Ion Effect § If one of the ions in a solution equilibrium is added to the solution, the solubility of the salt will decrease. • Calculating Solubility with a Common Ion o What is the molar solubility of CaF 2 in 0.010 M Ca(NO 3) 2? CaF 2(s) ⇌ Ca2+(aq) + 2 F–(aq) K sp = [Ca2+][F–]2 = 3.9 × ...
