The reaction between sodium bromide (NaBr) and calcium hydroxide (Ca(OH)₂ ) is a double displacement reaction.

Here's why:

* Double Displacement: In this type of reaction, the positive and negative ions of two reactants switch partners.

* The Reaction:

* NaBr + Ca(OH)₂ → NaOH + CaBr₂

* Explanation:

* Sodium (Na+) from NaBr combines with hydroxide (OH-) from Ca(OH)₂ to form sodium hydroxide (NaOH).

* Calcium (Ca²+) from Ca(OH)₂ combines with bromide (Br-) from NaBr to form calcium bromide (CaBr₂).

Important Note: This reaction is an equilibrium reaction, meaning it doesn't go to completion. The products (NaOH and CaBr₂) will also react to form the reactants (NaBr and Ca(OH)₂) to some extent.
