reactant
B: (NH4)2C2O4 (aq) → 2 NH4+ (aq) + C2O42- (aq)
D: CaCl2 (aq) → Ca2+ (aq) + 2 Cl- (aq)
Problem Details
| Solution | Solute | Color of Solution |
| A | Na2CrO4 | Yellow |
| B | (NH4)2C2O4 | Colorless |
| C | AgNO3 | Colorless |
| D | CaCl2 | Colorless |
When these solutions are mixed, the following observations are made:
| Experiment Number | Solutions Mixed | Result |
| 1 | A+B | No precipitate, yellow solution |
| 2 | A+C | Red precipitate forms |
| 3 | A+D | Yellow precipitate forms |
| 4 | B+C | White precipitate forms |
| 5 | B+D | White precipitate forms |
| 6 | C+D | White precipitate forms |
Write a net ionic equation for the reaction that occurs in each of the experiments. Identify the precipitate formed, if any, in each of the experiments.
Write a net ionic equation for the reaction that occurs in the experiment 5.
