explain redox with an reaction small answer please
Answers
Answer:
Redox reaction involves both oxidation and reduction of two compounds but within a same reaction
Explanation:
In redox reaction oxidation (removal of electron) and reduction ( addition of electron) take place simultaneously in two compounds but not in one compound. When both oxidation and reduction take place within one compound it is known as disproportionation reaction.
Example of redox reaction is
CuO+H2----->Cu+H2O
Here copper get reduced and hydrogen get oxidised

Answer- The above question is from the chapter 'Redox Reactions'.
Given question: Explain redox with an reaction.
Answer: The word 'Redox' has been derived from 'Red' which means Reduction and 'ox' meaning Oxidation.
It suggests that Oxidation and Reduction reactions go hand in hand.
The process of reduction involves-
1. Removal of oxygen from a substance.
2. Addition of hydrogen to a substance.
3. Gain of electrons in a substance.
4. Gain of electropositive element in a substance.
5. Removal of electropositive element from a substance.
6. Decrease in the oxidation number of a substance.
The process of oxidation involves-

3. Loss of electrons in a substance.
4. Removal of electropositive element from a substance.
5. Gain of electropositive element in a substance
6. Increase in the oxidation number of a substance.
Example:
ZnO + C → Zn + CO
Here, ZnO has been reduced as oxygen is removed from it.
C has been oxidised.
