When ammonium chloride (NH4Cl) and lead acetate (Pb(CH3COO)2) are mixed in a water solution, several chemical reactions can occur. Here are the potential reactions:
Double Displacement Reaction: NH4Cl + Pb(CH3COO)2 → PbCl2 + 2CH3COONH4
In this reaction, the ammonium chloride and lead acetate undergo a double displacement reaction. The ammonium ion (NH4+) from ammonium chloride combines with the acetate ion (CH3COO-) from lead acetate, forming ammonium acetate (CH3COONH4). Simultaneously, the chloride ion (Cl-) from ammonium chloride combines with the lead(II) ion (Pb2+) from lead acetate, forming lead(II) chloride (PbCl2). Both products are soluble in water.
Precipitation Reaction: NH4Cl + Pb(CH3COO)2 → PbCl2 (s) + 2CH3COONH4
Alternatively, a precipitation reaction can occur if the concentrations of the chloride ion and lead(II) ion are high enough. In this case, lead chloride (PbCl2) precipitates as a solid, while ammonium acetate remains in solution.
It's important to note that the actual reactions and the resulting products may depend on the specific concentrations and conditions of the solution, such as pH and temperature. Additionally, it's crucial to handle lead compounds with caution, as they can be toxic.
