1. You have a solution that you believe contains either ANO, or Fe(NOX). Describe a test that will let you confirm which is present. Describe the test in detail, and include a chemi- cal equation. 2. Would any of the tests you have used let you determine if a solution contained the potas- sium ion, K+? Either identify a test, or explain in detail why such a test is not possible using the simple methods described here. 3. A sample...

procedure and test result
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...

Microscale techniques: In today's experiment we will be using very small amounts of chemical reactants. This method is generally less expensive and more environmentally-friendly than traditional "test tube" chemistry. Some of the waste products produced in today's experiment, particularly those containing lead and barium, are harmful to the environment. By using such small amounts of chemical reactants we generate far less waste than by using larger scale methods. Procedure 1. Put on your safety goggles. Be sure to wear them...
