Question

distinguish between lead nitrate and zinc nitrate using alkali

Answer 1

Hey dear,

● Answer -
Lead nitrate and zinc nitrate can be distinguished by adding ammonium hydroxide to both.

● Explanation -
- When NH4OH is added to zinc nitrate, double precipitation reaction occurs giving white ppt of ammonium nitrate.
Zn(NO3)2 + 2NH4OH → Zn(OH)2 + (NH4)2NO3

- When NH4OH is added to lead nitrate, no change is observed.
Pb(NO3)2 + NH4OH → NO REACTION
