Question

इलेक्ट्रान खोना तो अपचयन अर्थात क्या है ? 10 वीं कक्षा​

Answer 1

Gain of electrons is called reduction

e.g. Zn 2+ + 2e------》 Zn

Here, the oxidation number of Zn in LHS is +2 and that of RHS is 0. So, the oxidation number. On the gain of electrons decreases and there is a decrease.

The loss of electrons is called oxidation

e.g. Mn 3+ -----》Mn 5+ + 2e-

Here, oxidation no. The LHS has +3 for Mn and the RHS has +5. So, oxidation no. On the loss of electrons increases and oxidation occurs.
