you scrub using the back of the toothbrush. It helps take out the white stuff on your tongue.
Go see a doctor. You either have an infection (white stuff on the surface of the tongue) or may have injured something (a tongue should be pink if it has adequate blood flow.)
The blackish-red stuff that forms on old ketchup bottles is typically a result of oxidation and microbial growth, which indicates a chemical change. This change alters the chemical composition of the ketchup, leading to the formation of new substances. In contrast, physical changes do not involve changes in chemical identity. Therefore, this phenomenon is a chemical change.
