Solution Steps

Step 1: Identify the Type of Reaction

To determine the type of chemical reaction, we need to analyze the reactants and products. The given reaction is:

\[ 3 \mathrm{CaSO}_{4} + 2 \mathrm{AlBr}_{3} \rightarrow 3 \mathrm{CaBr}_{2} + \mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3} \]

Step 2: Analyze the Reactants and Products

In this reaction, we have two compounds, \(\mathrm{CaSO}_{4}\) and \(\mathrm{AlBr}_{3}\), reacting to form two new compounds, \(\mathrm{CaBr}_{2}\) and \(\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}\).

Step 3: Determine the Reaction Type

This reaction involves the exchange of ions between two compounds, resulting in the formation of two new compounds. This is characteristic of a double replacement (or double displacement) reaction.

Final Answer

The reaction is a \(\boxed{\text{double replacement}}\) reaction.
