Solution
| Sr. No. | Ferric ions (Fe3+) | Ferrous ions (Fe2+) |
|---|---|---|
| 1. | A reddish-brown precipitate is formed with sodium hydroxide solution. | A dirty green precipitate is formed with sodium hydroxide solution. |
| 2. | The precipitate formed is ferric hydroxide, Fe(OH)3. | The precipitate formed is ferrous hydroxide, Fe(OH)2. |
| 3. | A reddish-brown precipitate is formed with ammonium hydroxide solution. | A dirty green precipitate is formed with ammonium hydroxide solution. |
| 4. | Thus, the reddish-brown precipitate confirms the presence of Fe3+ ions. | Thus, the dirty green precipitate confirms the presence of Fe2+ ions. |
