Analysis of Observations
6-8
Exercise #1. For Reactions #1 through #4: Compare the cations and anions used in 1-4. Choose the one cation and one anion that appear to be present and required for the common observation. Write a sentence summarizing your observation highlighting the required cation and anion and the common observation.
H+(aq)+CO32-(aq) yields effervescence
Exercise #2.A. For reactions #5 through #7: Compare the cations and anions used in 5-7. Choose the one cation and one anion that appear to be present and required for the common observation. Write a sentence summarizing your observation highlighting the required cation and anion and the common observation.
Exercise #2.B. For reactions #11 and #12: Study and report on the visible effect of acid on the new product compound from #6 and #7.
Exercise #3.A. For reactions #8 through #10: Compare the cations and anions used in 8-10. Choose the one cation and one anion that appear to be present and required for the common observation. Write a sentence summarizing your observation highlighting the required cation and anion and the common observation.
Exercise #3.B. For reactions #13 through #15: Study and report on the visible effect of acid on this new product compound from #8, #9, and #10.
Exercise #4.A. For reactions #16 through #19: Study the combinations and identify an anion participant which pushes the dye to be the new color that you saw. Write a descriptive sentence in the form "Dye plus _(anion) yields (new color)".
Exercise #4.B. For reactions #16 through #19: Study and report on the visible effect of acid on the dye color from #16 through #19. Write in the form "Acid plus (color) yields (new color).
Exercise #5. For reactions #20 through #22: Compare the cations and anions used in 20-22. Choose the one cation and one anion that appear to be present and required for the common observation. Write a sentence summarizing your observation highlighting the required cation and anion and the common observation.
Exercise #6.A. For reactions #23 through #25: Compare the cations and anions used in 23-25. Choose the one cation and one anion that appear to be present and required for the common observation. Write a sentence summarizing your observation highlighting the required cation and anion and the common observation.
