Aim - To identify the acidic radical and basic radical from the given unknown organic salt .
Materials Required - Salt , Reagents , Equipment's
Physical Observations -
=> Color Of the Salt : White crystalline
=> Odor of the Salt : Characteristic pungent smell
=> Solubility of the Salt : Soluble in Water
Observation Table -
TABLE 1 : Table to test for basic radical for the organic unknown salt.
| EXPERIMENT | OBSERVATION | INFERENCE |
|---|---|---|
| Salt + NaOH | Pungent Smell ( ammoniacal smell) |
'0' Group Present (may be NH4+) |
| Salt + NaOH + rod dipped in conc.HCl near mouth of tube |
White ppt. appear | NH4+ confirms |
| Salt + Water + Nesslars Reagent | Orange - Brown Reddish color appears |
NH4+ confirms |
TABLE 2: Table to test for Acidic radical for the organic unknown salt.
| EXPERIMENT | OBSERVATION | INFERENCE |
|---|---|---|
| Salt in Test Tube + dil. H2SO4 |
No Required Effect | dil. H2SO4 group is absent |
| Salt in Test Tube + conc. H2SO4 |
Suffocating Fumes | conc. H2SO4 group present (maybe Cl-) |
| Salt + NaOH + rod dipped in conc.HCl near mouth of tube |
White ppt. appear | NH4+ confirms |
| Salt + Water + Nesslars Reagent | Orange - Brown Reddish color appears |
NH4+ confirms |

Result - In the given salt, the acidic radical (anion) is Cl- and the basic radical (cation) is NH4+. Hence the given salt is NH4Cl (Ammonium Chloride).
Precautions - Wash the apparatus before use.
- Add the related reagents carefully.
- Observe the color and the effects carefully.
- Handle the acids carefully.
- Use Protection Equipment's like Glasses and Lab Coats.
Conclusion - Through this experiment, the acidic and basic radicals present in Ammonium chloride (NH4Cl) were successfully detected. The reactions with sodium hydroxide, hydrochloric acid, barium chloride, potassium iodide, sulfuric acid, and calcium hydroxide provided distinct observations, indicating the presence of both acidic and basic radicals in the salt. This experiment helps enhance the understanding of acid-base reactions and their detection in a practical setting, which is crucial for Class 12 CBSE Chemistry students.
