Drag a test tube from the box and place it on the metal test tube stand. You can then click on the bottle of Gag+ ion solution on the shelf to add it to the test tube. B. Click on the Divide button on the edge of the lab bench four times to make four additional test tubes containing Gag+. With one test tube in the metal stand and four others in the blue rack, click on the Niacin bottle on the reagent shelf and observe what happens in the window at the top left. Record your observation in the table above. If the solution remains clear, record NOR for no reaction.
Drag this test tube to the red disposal bucket on the right. C. Drag a second tube from the blue rack to the metal stand. Add NAS, record your observations and discard the tube. Continue with the third, fourth and fifth tube, but add Noah, Nassau, and Niacin respectively. Record your observations and discard the tubes. When you are finished, click on the red disposal bucket to clear the lab. D. Repeat steps a-c for five test tubes of Pub+ and Ca+. Record your observations in the data table. If no precipitate forms write NOR for no reaction. 3. What happens in grid space d?
What other reactions give similar results? Is it necessary to write an equation when no reaction occurs? Explain. There was no reaction. H, L, N, and O all had similar chemical reactions to D. Yes, because it is important to prove no reaction occurred. 4. Write balanced equations for all precipitation reactions you observed.
