Nitric acid oxidizes sulfide ion to sulfur. Explain on the basis of net ionic equilibrium equations and LeChatelier's principle why CuS dissolves more readily in HNO, than in HCI. 3. means of appropriate calculations, determine whether the nickel precipitate obtained at pH 8 was Ni(OH)2 or NiS 4.

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...

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...
