How Does Redox reaction (Change Fe3+ to Fe2+) Work?

Redox reactions are like a game where electrons go on a little journey from one atom to another, in this case, turning Fe³⁺ into Fe²⁺.

Imagine you're playing with your friends in a park. One of them has three candies and wants to share, but they only have two candies left after giving one away. That’s like Fe³⁺ becoming Fe²⁺, it loses an electron (like losing a candy).

Now think about a group of friends who are really good at sharing. They take an extra candy from someone else to make sure everyone has enough. That’s like another atom gaining an electron, which is the opposite part of the redox game.

In this case, Fe³⁺ (iron with a +3 charge) becomes Fe²⁺ (iron with a +2 charge). It does that by losing one electron, just like you might lose a candy to your friend. This is called reduction, not because it gets smaller, but because it loses a positive charge.

Meanwhile, another atom or ion may be doing the opposite: gaining an electron, which makes it more negative, kind of like getting that extra candy from your friend! That part is called oxidation.

So together, they play this fun game of giving and receiving electrons, and that’s how a redox reaction works!
