The purplish-red colour of meat is a result of the presence of myoglobin. Iron has an oxidation state of +2 in myoglobin and when it is oxidized to Fe3+ it will produce a brown colour.
This change is called oxidation (increase of ox. state) or reduction (decrease)
There are two chemical changes in this series. Oxidation always involves chemical change. Electrolysis does too.
Natural rubber is typically a milky white colour when it is harvested from rubber trees. However, it can also have a yellow tint due to oxidation over time.
The chemical formula of this is MnO2.It is brown in colour. The oxidation number of Mn is 4 in this compound.
They involve either transfer of electrons, or a change in the oxidation state of some atoms involved.
As the dye from the food colouring seeps into the meat connective tissue thus changing the colour of the meat
often the oxidation number is changed. Sometimes the conjugation would change in an organic. Tow things mainly account for colour. Conjugation and lone pairs
Oxidation agents can affect natural and artificial color pigments by breaking down the color molecules and causing them to change in appearance. In natural pigments, oxidation agents can lead to color fading or browning. In artificial pigments, oxidation agents can cause color loss or changes in hue.
The oxidation state of an element with oxidation state 0 cannot change, as it already has a balance of electrons.
The Colour of Chum Meat is Red.

True. A change in oxidation number occurs when there is a transfer of electrons from one atom to another, leading to a change in the oxidation state of an element in a chemical compound.
All oxidation is a chemical reaction.
In S2O82-, each S atom has an oxidation number of +5. In SO42-, the oxidation number of S is also +5. There is no change in oxidation number for sulfur when transitioning from S2O82- to SO42-.
