Silver chloride is insoluble in water and form a white color precipitate in water. If it is explained in other way, you can see a white color solid is deposited at the bottom of the aqueous solution. You can verify AgCl's solubility by checking its solubility value and solubility product value.
When solubility and solubility product are too small, we can say a compounds has a less chance to dissolve.
When silver chloride as a solid (not as a precipitate in water) at room temperature, it is a white crystalline solid.
Solubility and solubility product are good points to understand the solubility of a compound and they can be used to AgCl too.
Solubility of AgCl is 520 µg/100 g of water at 500C. So it is a very low value and prove furthermore, AgCl is a precipitate in water.
Ksp of AgCl is 1.7 *10-10 mol2 dm-6 which is also low and again tells us AgCl is not soluble in water.
When AgNO3 is mixed with aqueous NaCl solution, AgCl white precipitate is deposited at the bottom of the aqueous solution. Also sodium nitrate (NaNO3) is given as the other salt.
NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq)
AgNO3 is a soluble aqueous colourless solution.
In this section, we are going to find out, in which solutions AgCl will be dissolved?
AgCl is soluble in aqueous ammonia solution and give [Ag(NH3)2]Cl coordination complex compound. This [Ag(NH3)2]+ is a colourless solution.
But when solution is acidified, again AgCl precipitate forms.
When excess concentrated HCl is added to AgCl precipitate, precipitate dissolve and give colourless solution.
Note that, AgCl is not soluble in dilute acids.
If you want to get proved AgCl is insoluble in water, compare its solubility and NaCl's solubility in water.
Silver chloride, silver bromide and silver iodide are precipitates and very useful in identification of halide ions in qualitative analysis of inorganic chemistry. Also they have colors when they form precipitates.
|Silver halide name
|light yellow / pale yellow
AgCl is not soluble in alcohols but soluble in alkali cyanide solutions.
No. Silver chloride (AgCl) is not soluble and there is very less silver and chloride ions in the aqueous phase.
AgCl is also not soluble in water, because the forces favouring formation of silver hydroxide (AgOH) are too weak to break the ionic bonds between silver and chlorine in AgCl. That means bond between silver cation and chloride ion is strong.
Silver chloride does not react with nitric acid. Therefore, AgCl is not soluble in nitric acid
What are the correct statements of followings about silver?
Third and fourth statements are correct.
Yes. AgCl, white precipitate dissolve in aqueous ammonia solution and form colourless [Ag(NH3)2]+ coordination complex.
