Sn2+ looses 2 electrons in a reaction. What will be the oxidation number of tin after the reaction?
Question
Sn<sup>2+</sup> loses 2 electrons in a reaction. What will be the oxidation number of tin after the reaction?
Solution
The oxidation number of tin (Sn) after losing 2 electrons in a reaction will be +4. Here's why:
- Tin (Sn) starts with an oxidation number of +2 (as given by Sn2+).
- In a reaction, if an atom loses electrons, it is oxidized and its oxidation number increases. This is because electrons are negatively charged, so losing electrons results in a more positive charge.
- Since tin (Sn) loses 2 electrons, its oxidation number increases by 2.
- Therefore, the oxidation number of tin after the reaction is +2 + 2 = +4.
