What are the colors of ferric oxide, ferric chloride, ferric oxide and copper oxide respectively

It needs to be more accurate to distinguish just by color because color has something to do with concentration. Take four kinds of liquid to add potassium thiocyanate, and turn it into blood-red ferric chloride. The color is relatively dark after continuing to deepen or unchanged ferric chloride and potassium thiocyanate complex. The other two dark colors are potassium dichromate, and the lighter ones are potassium chromate. Guess the complex of ferric chloride and potassium thiocyanide at the far left. Add one drop to other samples. The most apparent color darkening is ferric chloride. The two dark colors are potassium dichromate, and the lighter ones are potassium chromate. Ferrous oxide, chemical form FeO. It is one of the oxides of iron. Its appearance is a black powder consisting of iron with an oxidation state of +2 covalently bound to oxygen. Ferric oxide, chemical formula Fe2O3. Also known as burning limonite, ochre, iron Dan, iron red, red powder, and Venetian red (the main component of iron oxide). , soluble in strong acid, medium strong acid, and the appearance of reddish-brown powder. Ferric oxide is often called iron oxide, which is reddish brown, ferric oxide is black, and ferric hydroxide is reddish brown. Oxidation: In a narrow sense, the chemical reaction of oxygen with other material elements is called oxidation. Oxidation is a vital chemical unit process. Oxidation is the process by which the atoms of the oxidized substance lose electrons, and the oxidizing agent gains them, no matter what the oxidizing agent is. Traditionally, it refers to the process of combining a sense with oxidation to form an oxide, which is the process of being oxidized by "oxygen"; It also includes things that contain hydrogen, in which hydrogen atoms are oxidized to make water, which is the process by which hydrogen atoms are stripped away by oxygen, also known as oxidation. Human metabolism is also like oxidation, which means that the human body rusts daily, and the rust produced is called "free radicals" in medicine.
