Verified step by step guidance

Identify the reactants and products in the chemical equation: The reactants are 3 Ca(OH)_2 (aq) and Al_2(SO_4)_3 (aq), and the products are 3 CaSO_4 (s) and 2 Al(OH)_3 (s).

Recognize the states of matter: The reactants are in aqueous form (aq), and the products are in solid form (s), indicating a precipitation reaction.

Understand the concept of double displacement reactions: In a double displacement reaction, the cations and anions of two different compounds switch places, forming two new compounds.

Analyze the exchange of ions: In this reaction, the calcium ions (Ca^2+) from calcium hydroxide (Ca(OH)_2) combine with sulfate ions (SO_4^2-) from aluminum sulfate (Al_2(SO_4)_3) to form calcium sulfate (CaSO_4), and the aluminum ions (Al^3+) combine with hydroxide ions (OH^-) to form aluminum hydroxide (Al(OH)_3).

Conclude the type of reaction: Since the ions are exchanged between the two reactants to form two new products, this is a double displacement reaction.
