The reaction is: AgNO3 + KCl = AgCl + KNO3
The precipitate is silver chloride.
When clhlorine is added to silver nitrate a milky white precipitate of Silver Chloride is formed. Potassium nitrate is also formed. When chlorine is added to potassium chloride nothing visible happens but the solutiuon become more acidic.
This compound is potassium chloride.
Lead nitrate + potassium sulfate ---> Lead sulfate + Potassium nitrate
Due to the potassium ion in potassium nitrate, any firework composition made with potassium nitrate would sport a purple/violet color, unless a strong colorant compound like strontium chloride is added to the composition.
It becomes Barium Nitrate combined with Silver Chloride
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
silver chloride should precipitate out.
Ag(NO3)(aq) + KI(aq) ---> K(NO3)(aq) + AgI(s)
Silver Chloride as a milky white solid, amd sodium nitrate
If the silver nitrate and ammonium chloride are both in solution when mixed, the very sparingly soluble silver chloride precipitates as a solid, leaving ammonium nitrate in the solution.
If chloride is present silver chloride with get precipitated..
Any reaction occur.
