Which fluoride salts are soluble?
Which fluoride salts are soluble?
Rule: Fluoride salts are frequently insoluble, including BaF2, MgF2 and PbF2. Exception: Group I fluoride salts are soluble. Rule: Silver salts are insoluble. Exceptions: Silver salts AgNO3 and Ag(C2H3O2) are soluble.
Are fluoride ions soluble?
Inorganic fluorides are generally not flammable. Soluble inorganic fluorides can react slowly with water to form hydrofluoric acid. Unlike other hydrogen halide acids, the anion (fluoride ion) is quite reactive, and can form fairly insoluble salts with alkaline earth metals such as calcium and magnesium.
Which salt has the highest solubility in water?
table salt or sodium chloride( NaCl) has highest solubility in water.

Is silver fluoride soluble?
Unlike the other silver halides, AgF is highly soluble in water (1800 g/L), and it even has some solubility in acetonitrile.
Is silver fluoride soluble or insoluble?

How do you know which salt is more soluble?
If there two rules appear to contradict each other, the preceding rule takes precedence.
- Salts containing Group I elements (Li+, Na+, K+, Cs+, Rb+) are soluble .
- Salts containing nitrate ion (NO3-) are generally soluble.
- Salts containing Cl -, Br -, or I – are generally soluble.
- Most silver salts are insoluble.
How do solubility of salts compare?
The relative MOLAR solubility of salts (saturated solution) can be determined by comparing Ksp values. The greater the Ksp the more ions are in solution, hence the greater the molar solubility. However, you can only directly compare salts that give equivalent numbers of ions in solution.

Is silver fluoride soluble in ammonium hydroxide?
The silver iodide is so insoluble that the ammonia won’t lower the silver ion concentration enough for the precipitate to dissolve….
| original precipitate | observation |
|---|---|
| AgI | precipitate is insoluble in ammonia solution of any concentration |
Why other silver halides are insoluble in water but silver fluoride is soluble in water?
Solubility is a substance’s ability to be dissolved. The substance that is dissolved is called a solute, and the substance it is dissolving in is called a solvent. For example among; the halides of Silver, Ag+, the fluoride ion in Silver Fluoride (AgF) is least polarized and hence it is soluble in water.
How soluble is fluoride?
Calcium fluoride (CaF2) is a colourless solid that is relatively insoluble in water and dilute acids and bases. Sodium fluoride (NaF) is a colourless to white solid that is moderately soluble in water.
What is solubility of fluoride?
WaterFluoride / Soluble in
Is sodium fluoride soluble or insoluble?
Sodium fluoride is a colorless crystalline solid or white powder, or the solid dissolved in a liquid. It is soluble in water. It is noncombustible.
Which salts are the most soluble?
The correct answer is Sodium. The solubility is the ability of a compound, it may be a liquid, solid or gaseous substance to dissolve in the solvent and there is a formation of a solution.
Why are some salts more soluble than others?
That’s partly due to the fact that the ions in sodium chloride, Na+ and Cl-, have lower charges than the ions in calcium carbonate, Ca2+ and CO32-. The higher the charges on the ions, the stronger their electrostatic attraction for each other, and the harder it is for the water to pull them apart.
How do you tell which salt is more soluble using KSP?
The relative MOLAR solubility of salts (saturated solution) can be determined by comparing Ksp values. The greater the Ksp the more ions are in solution, hence the greater the molar solubility.
