Question

When a solution of sodium carbonate is added to a solution of aluminum chloride what type of reaction

Answer 1

Answer:

$\boxed{ \text{A double displacement reaction} }$

Explanation:

In a double displacement reaction, the metal cations change partners with the anions.

3Na₂CO₃(aq)  + 2AlCl₃(aq) ⟶ 6NaCl(aq) + Al₂(CO₃)₃(s)

This is also a precipitation reaction, because the aluminium carbonate is insoluble and precipitates from solution.
