Diffrence between displacement and double displacement reaction |
|
Answer» DISPLACEMENT REACTION-->the reaction in which more reactive element displaces the less reactive element is known as displacement reaction........... ................... For ex---->Zn+CuSO4---------->ZnSO4+Cu. DOUBLE DISPLACEMENT REACTION-->the reaction in which two ionic compounds exchange each other and form new compounds is known as double displacement reaction........... ................. For ex-->AgNO3+NaCl-----:>AgCl+NaNO3. In displacement reaction a more reactive elelement displaces a less reactive element from it\'s compound wheras in double displacement reaction, two compounds combine by an exchange of their ions only to form new compounds. |
