An unknown salt consists of two types of cations and one type of anion
An unknown salt consists of two types of cations and one type of anion. The possible anions include chloride, Cl-, carbonate, CO32-, sulfate, SO42-. The possible cations include Group 1A cations, K+ and Na+, and Group 2A cations, Ca2+ and Sr2+.
a) After dissolving the unknown in 20 mL of DI water, you add 0.5 mL of 0.05 M AgNO3 and observe a precipitate. What are the possible precipitates that are formed? Write the net ionic equations for the reactions.
b) When HCl is added to your unknown, bubbles are observed. What can you conclude from this observation and from your observation in part (a) of this question? Identify the anion in this unknown (only one anion). What is the gas produced that causes the bubbles to form?

It is important to think through the reactions that are occurring (or not occurring) and determine how you can rule out the presence of a certain metal ion or how you can posi- tively identify its presence. Use the Solubility Table 1 and Appendix 1 of this manual to understand the precipitation réactions that are observed. You need to consider both the anion and the cation that react to form a given precipitate. The color and the general ap- pearance...

QUESTIONS 1. The first line in the procedure states that all of the cations have either nitrate or chloride as the counter lon. Explain why all of the cations have either nitrate ion or chloride ion as the counter ion. Why are other anions not used? 2. The second line in the procedure states that all of the anions have either sodium or potassium ion as the counter ion. Explain why all the anions have sodium...

Zinc forms the cation, Zn2+. A mystery anion X is represented as X2. Given this information, what is the molecular formula of the salt it forms with zinc? (Chemical formula use subscript numbers, but for this question any required numbers may be formatted normally. Also, do not insert any spaces between the elements.) Answer: Library Home Students According to the VSEPR electron pairs in the valence energy level repel each other and are therefore arranged as far apart as possible....

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...
