A student is given a solution of a single ionic compound. The student carries out three tests on the solution.
Table: The tests carried out on the solution and the observations made
| Test | Observation |
|---|---|
| Flame test | yellow flame |
| Sodium hydroxide solution added | no precipitate |
| Dilute nitric acid and silver nitrate solution added | yellow precipitate |
Name the metal ion in the solution. Use Table.
Name the negative ion in the solution. Use Table.
Name the compound in the solution.
Explain why no precipitate formed when sodium hydroxide solution was added.
