Purposes of Experiment: To synthesize a transition metal complex‚ potassium tris (oxalate)ferrate(III) trihydrate in a two step process‚ to learn new laboratory techniques such as decantation‚ recrystallization‚ gravity and suction filtration. Also the purpose of the experiment is to determine the actual‚ theoretical‚ and percent yields of product‚ and characterize the final compound by determining the number of waters of hydration by gravimetric analysis List of Observations: After adding

Investigating the Determining Characteristics of Cations and Anions Chem 111 Sec 560 Introduction: The purpose of this lab was to study the specific characteristics of cations and anions‚ and ultimately to be able to identify an unknown substance based on our studies and tests using the logic trees developed through the experiment. A logic tree is a graphical display of the findings from this lab which‚ through a series of yes/no questions‚ elimination

Chapman et.al (2009) studied the local impact of hoisted point sources on late spring aerosol driving and cloud-aerosol cooperations‚ in northeastern North America‚ was studied by utilizing the WRF-Chem community model. The immediate impacts of mist concentrates on approaching sun powered radiation were recreated utilizing existing modules to relate aerosol sizes and chemical composition to airborne optical properties. Direct impacts were reenacted by including a prognostic treatment of cloud bead
