Question

Why is precipitation reaction consider as double displacement reaction explain?

Answer 1

Refer to the explanation.

Explanation:

A double displacement (double replacement or metathesis) reaction can have three possible products; a precipitate, an insoluble gas, or water (neutralization reaction). The solutions contain ionic compounds as solutes, and it is the ions that will react.

The general equation is:

`color(red)("A")color(green)("X") + color(magenta)("B")color(blue)("Y")` `rarr` `color(red)("A")color(blue)("Y") + color(magenta)("B")color(green)("X")`,

where:

`color(red)("A")` and `color(magenta)("B")` are cations, and `color(green)("X")` and `color(blue)("Y")` are anions. As you can see, the cations and anions switch partners in a double displacement reaction.

A precipitation reaction occurs when two solutions of ionic compounds are combined and they react to form an insoluble solid, which is the precipitate.
