formation between silver and ammonia: + Ag + 2NH3 A g(NH3 )2 + Kf = 1 .5 x 10 7 where Kf i s the formation constant (always >1 ‚ formation of the complex is highly favorable) Complex ion formation increases the solubility of sol ids in water. Example: Calculate the solubility of AgCl (1.6 x 10 + -10 ) in 1.0 M NH3 . AgCl A g + Cl - Ksp = 1.6 x 10 Ag + 2NH3 A g(NH3 )2 + Kf = 1 .5 x 10 + + AgCl + 2NH3 Ag(NH3 )2 + Cl - K = 2 .4 x 10

Whitish ppt stayed and did not dissolve‚ which is a positive confirmation for Hg2+2‚ therefore it contains Hg2+2. Identifying Ag+: 1) decanted the soln from Hg2+2 into another test tube and added 6M HNO3 until it became acidic by litmus paper test 2) no white ppt formed but soln was acidic‚ which is a negative confirmation because no white ppt was formed‚ therefore no Ag+ was contained The observations I made with the Pb+2 was the yellow ppt formed when K2CrO4 was added after the separation.

performed akin to room temperature in the laboratory ambience. X-ray and transmission electron microscopy analyses are performed to ascertain the formation of metallic and oxide nanoparticles. Individual nanoparticles having the dimensions of 10–25 nm (n-Ag) and 10–70 nm (n-TiO2) are found. The mechanism involved for the synthesis of metallic and oxide nanoparticles has also been discussed.
