Question

CuSo⁴+Zn--->ZnSo⁴+Cu this is ________reaction​

Answer 1

Answer:

displacement reaction.

Explanation:

Displacement reaction.

• In a displacement reaction, an ion (or an atom) in a compound is replaced by an ion (or an atom) of another element. It may be denoted as:

                                    X + YZ → XZ + Y

• Displacement reactions fit into two categories: metal displacement and non-metal displacement.

(a) Metal displacement:

• A metal in a compound can be displaced by another metal in the uncombined state.

• Metal displacement reactions find many applications in metallurgical processes in which pure metals are obtained from their compounds in ores.

• A few such examples are:

1. CuSO4(aq) + Zn (s) → Cu(s) + ZnSO4(aq)
2. V2O5 (s) + 5Ca (s) → 2V (s) + 5CaO (s)
3. TiCl4 (l) + 2Mg (s) → Ti (s) + 2 MgCl2 (s)
4. Cr2O3 (s) + 2 Al (s) →Al2O3 (s) + 2Cr(s)

(b) Non-metal displacement:

• The non-metal displacement redox reactions include hydrogen displacement and a rarely occurring reaction involving oxygen displacement.

• A few such examples are:

1. 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
2. Ca(s) + 2H2O(l) → Ca(OH)2 (aq) + H2(g)
3. 2H2O (l) + 2F2 (g) → 4HF(aq) + O2(g)
