Final answer:
Acids and bases can cause burns to the oral mucosa when ingested. Strong acids like hydrochloric acid and bases like sodium hydroxide have the potential to decompose proteins and lipids, resulting in chemical burns.
Step-by-step explanation:
Ingesting certain chemicals can cause burns to the oral mucosa. The two main types of chemicals that cause burns are acids and bases. Acids like hydrochloric acid, sulfuric acid, and nitric acid can cause burns when ingested. Bases like sodium hydroxide and potassium hydroxide also have the potential to cause burns when ingested. Strong acids and bases can decompose proteins and lipids in living tissues, leading to chemical burns.
