Question

5. What is the difference between displacement and double
displacement reaction? Write equation for these reaction
​

Answer 1

Answer:

displacement reaction : a reaction in which more reactive element displaces less reactive element are known as displacement reaction

ex - Zn + H2SO4 = ZnSO4 + H2

double displacement reaction : a reaction in which in which ions are exchanged are known as double displacement reaction

ex- Na2SO4 + BaCl2 = NaCl + BaSO4
