Why silver fluoride is soluble in water?
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. F (fluoride) is the most electronegative atom on the periodic table, so, AgF, is an ionic salt solubilized by surrounding water molecules and H bonding.
Is silver fluoride soluble or insoluble?
Silver Fluoride is a water insoluble Silver source for use in oxygen-sensitive applications, such as metal production.

Why is silver iodide insoluble in water?
Answer: Silver iodide has a lower baseline solubility in water than silver chloride, because the iodide ion, having lower charge density than chloride, is not solvated as effectively.
Is silver fluoride a precipitate?
Silver fluoride is soluble, so no precipitate is formed.
Is silver fluoride soluble in ammonia?
Silver fluoride is soluble, and so you don’t get a precipitate. Ammonia solution is added to the precipitates….

Why AgI is insoluble in water but AgF is soluble?
It is clear to you by periodic table that Iodide ion is much larger than fluoride and more polarizable. For this reason the covalent charecter of AgI is much higher than that of AgF according to Fajan’s Rule. So, AgI is insoluble while AgF is soluble in water.
Is silver iodide soluble or insoluble?
Silver iodide is insoluble in water and form a bright yellow precipitate in water. If it is explained in other way, you can see a bright yellow color solid is deposited at the bottom of the aqueous solution. You can verify AgI solubility by checking the solubility value and solubility product value.
Is silver iodide AgI soluble or insoluble?
Silver iodide, AgI , is an insoluble ionic compound, which basically means that when this compound is added to water, an equilibrium is established between the undissolved solid and the dissolved ions. Notice that every mole of silver iodide that dissolves produces 1 mole of silver cations and 1 mole of iodie anions.
Why does silver fluoride not form a precipitate?
Silver fluoride is soluble, and so you don’t get a precipitate. Ammonia solution is added to the precipitates.
Why is silver bromide insoluble in water?
It has to do with the relatively low electronegativity difference between silver and bromine; also a concept called “Fajan’s Rule,” which says that silver’s ionic radius is similar in size to halide ionic radii, meaning they can “snuggle up close” to each other, rendering them difficult to dissociate in water.
What is the solubility of silver ionic compounds?
Solubility. It is also unique among silver (I) compounds and the silver halides in that it forms the hydrates AgF. (H 2 O) 2 and AgF. (H 2 O) 4 on precipitation from aqueous solution. Like the alkali metal fluorides, it dissolves in hydrogen fluoride to give a conducting solution.
Is silver sulfate soluble in water?
In the case of silver sulfate, it is soluble to a relatively small extent. So when silver sulfate is added to water, some of the silver sulfate salt will form their ions (soluble in water) and some will not (not soluble in water). Hence, we call these salts sparingly soluble salts.
What is the formula for silver(I) fluoride?
Infobox references. Silver(I) fluoride is the inorganic compound with the formula AgF. It is one of the three main fluorides of silver, the others being silver subfluoride and silver(II) fluoride.
What are the optical properties of silver(I) fluoride?
Silver(I) fluoride exhibits unusual optical properties. Simple electronic band theory predicts that the fundamental exciton absorption for AgF would lie higher than that of AgCl (5.10 eV) and would correspond to a transition from an anionic valence band as for the other silver halides.
