The following equation is an example of which type of reaction? CuSO₄ + 2NaOH → Cu(OH)₂ + Na₂SO₄
Double displacement reaction
The given chemical equation is:
CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4
This equation represents a double displacement reaction. In this type of reaction, two compounds exchange ions to form two new compounds. Specifically, the sulfate (SO42-) ion from copper sulfate and the hydroxide (OH-) ion from sodium hydroxide exchange to form copper hydroxide and sodium sulfate.
Let's break down the reaction:
- CuSO4 dissociates into Cu2+ and SO42-.
- 2NaOH dissociates into 2Na+ and 2OH-.
- The Cu2+ combines with OH- to form Cu(OH)2.
- Na+ combines with SO42- to form Na2SO4.
Thus, the equation exemplifies a double displacement reaction.
