NaHSO₃ is the purifying agent.
Explanation:
- Benzaldehyde produced in the reactions need to be purified.
- Benzaldehyde is best purified with sodium bisulphite.
- Sodium bisulphite reacts with benzaldehyde to form an adduct.
- This form is highly soluble in water being ionic, and can be separated form other impurities.
- This then can be reacted with mild alkali to regenerate the benzaldehyde from the adduct.
- Benzaldehyde isn't much soluble in water, so can be collected easily.
