Colour of agcl

Solubility and solubility product are good points to understand the solubility of a compound and they can be used to AgCl too. Solubility of silver chloride in water Solubility of AgCl is 520 µg/100 g of water at 50 0C. So it is a very low value and prove furthermore, AgCl is a precipitate in water. Solubility product of silver chloride Ksp of AgCl is 1.7 *10 -10 mol 2 dm -6 which is also low and again tells us AgCl is not soluble in water. How AgCl precipitate is formed? When AgNO 3 is mixed with aqueous NaCl solution, AgCl white precipitate is deposited at the bottom of the aqueous solution. Also sodium nitrate (NaNO 3) is given as the other salt. NaCl (aq) + AgNO 3(aq) → AgCl (s) + NaNO 3(aq) AgNO 3 is a soluble aqueous colourless solution. Solubility of AgCl in other solutions In this section, we are going to find out, in which solutions AgCl will be dissolved? Solubility in ammonia solution AgCl is soluble in aqueous ammonia solution and give [Ag(NH 3) 2]Cl coordination complex compound. This [Ag(NH 3) 2] + is a colourless solution. But when solution is acidified, again AgCl precipitate forms. Is AgCl is soluble in concentrated HCl? When excess concentrated HCl is added to AgCl precipitate, precipitate dissolve and give colourless solution. AgCl dissolves in alkali cyanide solutions Note that, AgCl is not soluble in dilute acids. Why and how do you say AgCl is not soluble in water If you want to get proved AgCl is insoluble in water, compare its solubility and NaCl's ...

Silver nitrate can stain skin black for days—If any solutions, especially the 6M bases, are spilled on one's self, wash the affected area for at least 15 minutes. Discussion: A precipitation reaction occurs when a precipitant causes a chemical to fall out of solution. The remaining solution is called a supernate or supernatant. A very important stage in precipitation is the onset of nucleation. The creation of a solid particle includes the formation of a solid-solution interface, which r...

Silver chloride is described as a white crystalline chemical compound having the formula AgCl. Silver chloride, present in the test tube, turns purplish quickly, especially in the case of a sunny laboratory due to the silver chloride being split up into both chlorine and silver. Silver chloride can be prepared when the sodium chloride compound is added to the silver nitrate solution; there occurs a white precipitate of silver chloride. Silver chloride is also an example of a well-known salt stain, which is used to impart an amber colour to the glass. Chloro silver is the other name of silver chloride.

AgCl occurs naturally as the mineral chlorargyrite. Silver chloride converts to silver and chlorine, when subjected to sunlight or heating. AgCl adopts the fcc NaCl structure, in which Ag + ions are surrounded by octahedrons of six chloride ligands.
