Question- compare the color and ionic composition of the examined salt and their solutions. Is the cation or anion responsible for the salts color. Cite Specific experimental observation
Ionic compound= Nickel (II) Chloride
EXPERIMENTAL OBSERVATION- salt name- Nickel(II) Chloride / Dry salt color alone- Light green / Salt in Aqueous solution- lighter green.
NOTE- I understand that the water causes a jump and light is absorbed, also believe cation is. responsible. but the color itself did not really. change much which makes the question rather confusing.

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each 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 a product with chloride. Note that the formula of each product is determined by the charges of the ions,...

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...
