FAQs on Electron Exchange In Oxidation: Reduction Reactions Video Lecture - Chemistry for GCSE/IGCSE - Year 11
| 1. What is electron exchange in oxidation-reduction reactions? |  |
Ans. Electron exchange in oxidation-reduction reactions involves the transfer of electrons from one reactant to another. The reactant that loses electrons is oxidized, while the reactant that gains electrons is reduced.
| 2. How does electron exchange occur in oxidation-reduction reactions? | |
Ans. Electron exchange in oxidation-reduction reactions occurs through the transfer of electrons between reactants. This transfer leads to changes in the oxidation states of the elements involved.
| 3. What is the role of electrons in oxidation-reduction reactions? | |
Ans. Electrons play a crucial role in oxidation-reduction reactions by facilitating the transfer of charges between reactants. The movement of electrons is what determines whether a substance is oxidized or reduced.
| 4. How can you determine which reactant is oxidized and which is reduced in a reaction? | |
Ans. To determine which reactant is oxidized and which is reduced in a reaction, you can compare the oxidation states of the elements before and after the reaction. The element that increases in oxidation state is oxidized, while the element that decreases is reduced.
| 5. Can you provide an example of electron exchange in an oxidation-reduction reaction? | |
Ans. One example of electron exchange in an oxidation-reduction reaction is the reaction between iron and oxygen to form iron oxide. In this reaction, iron loses electrons (is oxidized) to oxygen, which gains electrons (is reduced).
