2 AgCl (s) + 2 NH4OH (aq) --> Ag2O (s) + H2O (l) +2 NH4Cl (aq)
With more NH4OH, the brown/black Ag2O dissolves forming the soluble salt Silver Di-amine hydroxide:
Ag2O (s) + 4 NH4OH --> 2 [Ag(NH3)2]OH + 3 H2O
I suspect that this reaction is reversible and the loss of NH3 would push the reaction to the left, which may occur naturally with time. This is a major problem as the precipitated Ag2O can further react with NH4OH to form Silver nitride, Ag3N:
2 NH4OH (aq) + 3 Ag2O (s) --> 2 Ag3N (s) + 5 H2O
Silver nitride can be a highly sensitive and powerful contact explosive, even when in solution. This has been ascribed to be the cause of many injuries, and as such, solutions of [Ag(NH3)2]OH should not be stored for safety concerns.

How would you separate lead chloride from mixture of lead chloride and silver chloride?
silver chloride is soluble in ammonia, lead chloride is only slightly soluble in ammonia
What is observe when aqueous ammonia is added in excess to a silver chloride solution?
The white precipitate of silver chloride will dissolve when aqueous ammonia is added.
How do you separate lead chloride and silver chloride?
Add ammonia solution to mix. Silver chloride dissolves leaving lead chloride behind.
Why silver chloride turns grey in sunlight?
Silver chloride turns grey due to decomposition reaction. This decomposition reaction is called photoletic decomposition. 2AgCl gives Ag + Cl2 (silver (silver) (chloride) Chloride)
What are the products of the double-replacement reaction between potassium chloride and silver acetate?
The products are Silver chloride (a white precipitate) and potassium ethanoate (acetate). NB THis is a classic test for halides.
What sign of a chemical reaction does sodium chloride have?
For example the product of the reaction between sodium chloride and silver nitrate is the insoluble silver chloride.
What would be observed when a fresh precipitate of silver chloride is treated with excess ammonia solution?
When you treat silver chloride with excess ammonia solution, Diamine silver (I) chloride is formed . The reaction involved is- AgCl + NH(3) --->Ag( (NH(3)) 2)(+) + Cl(-).What you will observe is that AgCl is insoluble, but after adding ammonia it becomes soluble because of above reaction.
What is the reaction between cadmium chloride and silver chloride?
There would be no reaction because they are both chlorides.
How would you separate lead chloride from mixture of lead chloride and silver chloride?
silver chloride is soluble in ammonia, lead chloride is only slightly soluble in ammonia
What is observe when aqueous ammonia is added in excess to a silver chloride solution?
The white precipitate of silver chloride will dissolve when aqueous ammonia is added.
Is there is any chemical reaction between NaCl and AgNO3?
If both silver nitrate and sodium chloride are dissolved in water and mixed, there will be a reaction to precipitate silver chloride. Solid silver nitrate and sodium chloride will not normally react.
What is reaction between silver iodide and ammonia?
2AgI+2NH3 give you 2AgNH3 + I2.Reaction only occurs when ammonia (NH3) is added in excess.
How do you separate lead chloride and silver chloride?
Add ammonia solution to mix. Silver chloride dissolves leaving lead chloride behind.

Silver chloride equals silver plus chlorine?
No reaction
