In d, no reaction - Soul occured, and Pd soy at Caso will similarly farm reactions the nitrate solutions. What happens in grid space d? What other reactions give similar results? Is it necessary to write an equation when no reaction occurs? Explain. If no precipitate forms write NR for no reaction. Record your observations in the data table. Repeat steps a-c for five test tubes of Pb2+ and Cat. When you are finished, click on the red disposal bucket to clear the lab. Record your observations and discard the tubes. Continue with the third, fourth and fifth tube, but add NaOH, Na2SO4, and NaCl respectively. Add Na S, record your observations and discard the tube. Drag a second tube from the blue rack to the metal stand. Drag this test tube to the red disposal bucket on the right. If the solution remains clear, record NR for no reaction. Record your observation in the table above. With one test tube in the metal stand and four others in the blue rack, click on the Na:CO bottle on the reagent shelf and observe what happens in the window at the top left. Click on the Divide button on the edge of the lab bench four times to make four additional test tubes containing Agt. You can then click on the bottle of Ag ion solution on the shelf to add it to the test tube.
