CHG 3111 Unit Operation Gas-Liquid Separation Text Book: Chapter 10 Separation Processes Introduction: Many chemical and biological processes occur as a mixtures of different phases‚ gas‚ liquid and solid. To separate or remove one or more of the components from its original mixture‚ it must be contacted with another phase. The two phase pair can be gas-liquid‚ liquid-liquid or liquid-solid. When different phases are brought into contact‚ a solute or solutes can diffuse from on phase to the

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.

The Golden Ratio The Golden Ratio is a term (with an astounding number of aliases‚ including Golden Section and Golden Mean) used to describe aesthetically pleasing proportioning within a piece. However‚ it is not merely a term -- it is an actual ratio. The Golden ratio is a special number found by dividing a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part. It is often symbolized using phi‚ after the 21st letter

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.
