Solubility of the silver halides decreases down the group.
The solubilities of silver halides decreases down the Periodic Table:
- AgF :Ksp=205
- AgCl:Ksp=1.8×10−10
- AgBr:Ksp=5.2×10−13
- AgI :Ksp=8.3×10−17
What else can I help you with?
Cations that are insoluble halide salts?
Silver, lead, and mercury cations commonly form insoluble halide salts such as silver chloride (AgCl), lead(II) chloride (PbCl2), and mercury(I) chloride (Hg2Cl2). These salts are sparingly soluble in water and form precipitates when halide ions are added to their solutions.
Is silver nitrate or silver chloride or silver carbonate more soluble in a polar solvent?
Silver nitrate is soluble in water but chloride and carbonate are insoluble.
When photographic film is exposed to light the salt on the film breaks down what metal is formed?
The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"
What effect does silver nitrate solution have upon each of the halide salt solutions?
The product is a silver halide insoluble in water.
Is it true that the 2 main purposes of a fixing solution are to expose the silver halide crystals and turn the entire crystals into a block of metallic silver?
Yes, it is true that the two main purposes of a fixing solution in photography are to expose the silver halide crystals that have not been developed and to convert the remaining undeveloped silver halide into soluble compounds. This process ensures that only the developed silver crystals remain, turning them into a block of metallic silver, which is what creates the final image. The fixing solution effectively stabilizes the image, preventing further development and degradation.

Why is silver nitrate added to halide salts?
Silver nitrate is added to halide salts to test for the presence of halide ions. When silver nitrate is added, a precipitation reaction occurs where silver halide compounds are formed. The color of the precipitate that forms can help identify the type of halide ion present in the salt.
Is silver nitrate soluble or insoluble?
Silver nitrate is the most soluble in water of all common silver salts and is generally considered soluble, although it does have a saturation limit.
Is silver nitrate or silver chloride or silver carbonate more soluble in a polar solvent?
Silver nitrate is soluble in water but chloride and carbonate are insoluble.

What happens when Alkyl halide reacts with silver nitrate?
When an alkyl halide reacts with silver nitrate, a substitution reaction takes place where the halide ion is displaced by the silver ion to form a silver halide precipitate. The alkyl group remains unchanged in the reaction.

The product is a silver halide insoluble in water.

Is sodium iodide water soluble?
Yes. Simple alkali metal salts tend to be soluble with extremely few exceptions; most halides are likewise soluble. An alkali metal halide, such as sodium iodide, should be expected to be extremely soluble in water.
What is the word equation of photographic film?
The word equation for photographic film is: Silver halide crystals + light → Silver metal + halide ions.
What part of the silver halide crystal is most affected by light when film is exposed?
The exposed silver halide crystal within the film is most affected by light during exposure. When light hits the crystal, it triggers a chemical reaction that forms a latent image, creating the basis for the eventual image development process.
What is the most photosensitive silver halide?
Silver iodide is the most photosensitive silver halide due to its higher sensitivity to light compared to other silver halides such as silver chloride and silver bromide. This makes silver iodide ideal for use in high-speed photographic film and other light-sensitive applications.
