In transition metal complexes water as ligands form the coordinate covalent bods and is responsible to split the d-orbitals in to two groups in which transition of electrons produces colour when water is driven off the splitting of d-orbitals becomes vanished and colour disappear.

Why green color of feso4 changes when heated?
The green color of FeSO4 changes when heated because it undergoes a dehydration reaction. Heating causes the water molecules in the compound to be removed, leading to a change in the oxidation state of iron from +2 to +3, resulting in a color change.
What situations could occur in a hydrate?
Hydrates can experience dehydration when exposed to heat, causing them to lose water molecules and undergo a phase change. They can also undergo re-hydration when exposed to water vapor in the air, potentially leading to the formation of a hydrated compound again. Additionally, hydrates can exhibit shifts in color or physical properties due to the presence or absence of water molecules in their structure.
Is ripening fruit a physical or chemical change?
Ripening fruit is a chemical change because it involves the breakdown of complex molecules in the fruit resulting in changes in color, texture, and flavor. This process is driven by enzymes and chemical reactions within the fruit.
When could color change be a result of a physical change?
A color change is only a chemical change if the change is permanent, if the color change is not permanent, then it is likely a physical change. Let's look at Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
Why is color change considered a chemical change?
Color change is considered a chemical change because it involves a transformation at the molecular level, where the chemical composition of the substance is altered, leading to a change in its color. This change is irreversible and indicates a chemical reaction has occurred.
What the color of of salt after crystallization?
Pure sodium chloride crystals are colorless.
