Answer: This reaction is an example of a double replacement reaction. In a double replacement reaction, the cations and anions of two different compounds switch places to form new compounds.
Let's break down the given reaction:
ZX2 (aq) + B₂EY 3 (aq) → BX (aq) + ZEY3 (s)
In this reaction, the cations ZX2 and B₂EY3 swap places. The result is the formation of new compounds, BX and ZEY3.
Double replacement reactions typically occur when two ionic compounds are combined in an aqueous solution. The positive ions (cations) from one compound switch places with the positive ions from the other compound, while the negative ions (anions) do the same. The resulting compounds may be in different physical states, such as solid (s), liquid (l), or aqueous (aq).
In this case, the reactants ZX2 and B₂EY3 are both in aqueous solutions (aq), and the product ZEY3 is a solid (s). This indicates that a double replacement reaction has occurred.
It is important to note that this type of reaction is also known as a metathesis reaction or a precipitation reaction, depending on whether a solid is formed or not.
