Question

Can a combination reaction be also a redox reaction?

Open in App

Solution

1. Combination reaction is a chemical reaction in which two or more substances combine to form a single substance.
X + Y → XY

2. Example:
Formation of calcium oxide.
2Ca(s) + O₂(g)→ 2CaO(s)
It is also a redox reaction. Here Ca is oxidised to Ca⁺² in CaO and O₂ is reduced to O^-2 in CaO.
3. So, we can conclude combination reaction can also be a redox reaction.
