Question

What does Barium chloride + Aluminum sulfate produce?

Answer 1

Precipitation reaction:

• A precipitation reaction is one in which two or more substances react to form one (or more) solid products.

Reaction between Barium chloride and Aluminium sulfate:

• When Barium chloride$\left({\mathrm{BaCl}}_2\right)$ reacts with Aluminium sulfate $\left({\mathrm{Al}}_2{\left({\mathrm{SO}}_4\right)}_3\right)$, a white precipitate of Barium sulfate $\left({\mathrm{BaSO}}_4\right)$ is formed along with Aluminium chloride $\left({\mathrm{AlCl}}_3\right)$.
• The chemical equation can be depicted as:

$$\begin{gathered} 3{\mathrm{BaCl}}_2\left(\mathrm{aq}\right)+{\mathrm{Al}}_2{\left({\mathrm{SO}}_4\right)}_3\left(\mathrm{aq}\right)\to 3{\mathrm{BaSO}}_4\downarrow +2{\mathrm{AlCl}}_3\left(\mathrm{aq}\right) \\ (\mathrm{Barium}\mathrm{chlroide})(\mathrm{Aluminium}\mathrm{sulfate})(\mathrm{Barium}\mathrm{sulfate})(\mathrm{Aluminium}\mathrm{chloride}) \end{gathered}$$

• This reaction is known as a precipitation reaction.
