to be your result if you were to perform this experiment and
why.
Part A: Determination of Factors Affecting the Relative Rates of Sy2 Reactions All test tubes must be dry. Effect of Structure of the Alkyl Halide Measure 2 mL of 15% sodium iodide in acetone into each of three clean, dry 10-cm test tubes.

was Zn(CN)2 but it is not a denim blue.
The Soluble Hydroxide Group: Analyze the Solution for the Presence of Znº and All 25. To test for All, add 10 drops of 6 M HNO, solution to Test Tube 5. Check the pH of the solution. If it is not acidic, add more 6 M HNO, dropwise until the solution becomes acidic. Add 6 M NH, solution dropwise until...

1. Write the chemical formulas for all the barium salts that can be formed in Part 1 Part 1A: Solubility of barium salts under neutral conditions 1. Using a clean disposable pipet, transfer 1 mL of Co-anion solution to a clean test tube and label the test as "Co?- neutral". Repeat this for the remaining anion solutions S0?-?,P03-?, NO3",C1-7,7- 'so that you will have six test tubes with six unique anion solutions. Use a different pipet for each anion solution,...

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...

PART B The operations in this part will take place in the hood. To avoid traffic problems, plan ahead and work efficiently to occupy the hood for a minimal time. After making a set of test tube additions, step back to mix the tubes and allow others to have access to the materials. Clean and rinse the four-inch (small) and six-inch (medium) test tubes from your drawer. Use three of the four-inch tubes to observe the colors of the halogen...

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.
