What is the type of reaction of this balanced equation?

Question

2NaOH(aq) + CaBr2(aq) ==> Ca(OH)2 + 2NaBr(aq)

Answer 1

You should include the phase for Ca(OH)2 as (s), so you'd have the following:

2NaOH(aq) + CaBr₂(aq) ==> Ca(OH)₂(s) + 2NaBr(aq)

This is a double replacement/displacement reaction

It is also a precipitation reaction since Ca(OH)₂ is precipitated as a solid

Answer 2

this represents a double displacement reaction, meaning that the positive ions and negative ions of two ionic compounds trade places to form two new compounds.
