You are given a colorless unknown solution that contains one of the following salts: NaA, NaB, NaC. in solution, each salt dissociates completely into the Na+ ion and the anion A-,B- or C-, whose properties are given ( B2 weakest oxidizing agent, then C2, then A2 the strongest oxidizing agent) The Na+ ion is effectively inert. Given the availability of solutions of A2,B2, AND C2, develop a simple procedure for IDing the salt that is present in your unknown.

Section Name Experiment 12 Advance Study Assignment: The Alkaline Earths and the Halogens I. As pure clements, all of the halogens are diatomic molecular species, Their melting points are: F,, 54 K: Br 266 K; and I, 387 K. Using the Periodic Table, predict as best you can the molecular Cl., 172 1 formula of elemental astatine, At, the only radioactive element in this family. Also predict whether it will be a solid, liquid, or gas at rOom temperature. Elemental...
Equation for Part A above
1. Write net-ionic equations for the following precipitation reactions: a) The reaction between barium nitrate and sulfuric acid. b) The reaction between calcium nitrate and sodium oxalate. 2. Elements A, B, and C exist as the diatomic molecules A2, B2, and C2. All act as oxidizing agents, i.e., they take electrons from other species. In aqueous solution, A2 is green, B2 is yellow, and C2 is red. When they have gained electrons from other species,...
1. Suppose you are given an unknown aqueous solution that contained one of the following cations AR', Ba", or Na'lons. You have available the following test solutions: 1 M sulfuric acid and 1 M hydrochloric acid. Explain how you would use these test solutions to determine the identity of the cation in the unknown solution. Using complete sentences and proper terms, explain the tests you would perform, the expected outcomes, and how the results would allow you to determine the...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
