Distinguish between a displacement and a double displacement
reaction. Write chemical equation
Answers
The reaction in which an atom or a set of atoms are displaced by another atom in a molecule is called displacement reaction. For instance, when Iron is added to a copper sulfate solution, it displaces the copper metal.
A + B – C → A – C + B
The above equation exists when A is more reactive than B.
A and B have to be either:
Halogens where C indicates a cation.
Different metals wherein C indicates an anion.
Chemical Displacement
●In a displacement reaction, a more reactive element replaces a less reactive element from a compound.
●Change in color takes place with no precipitate forms.
CuSO4+Fe → FeSO4+Cu{down arrow}
Chemical Double Displacement
●In a double displacement reaction, two atoms or a group of atoms switch places to form new compounds.
●Precipitate is formed.
MgCl2+Na2CO3 → MaCO3 {down arrow} +2NaCl
