Question

When a few drops of hcl are added to agno3 solution followed by addition of nh4oh solution

Answer 1

Here is your answer:

AgNO₃(aq)+NaCl(aq)→AgCl(s)↓+NaNO₃(aq)  

Silver chloride is as soluble as a brick, and precipitates from solution as a curdy white solid. The addition of aqueous ammonia will bring some (all?) of the precipitate back into solution as its ammonia complex.

AgCl(s)+2NH₃(aq)→[Ag(NH₃)₂]+Cl−(aq)↑

Answer 2

Explanation:

AgNO3 + HCl---->AgCl + HNO3

AgCl + NH4OH----->(Ag(NH3)2)Cl + 2H2O

So it firstly change Silver nitrate solution to AgCl as white ppt..

then gives water..........
