Hydrochloric Acid (shortened to H. Acid or ACID) is a miscellaneous item in Undertale Yellow that is required for progression in the Steamworks during a Neutral or Genocide Route. Made in the chemistry lab by combining hydrogen and chlorine, it can be used to melt through a locked door in the same room. It can also be used from the inventory, which causes Clover to drink it and immediately die.

Additional Uses

• Using the Hydrochloric Acid from the inventory results in unique death screen text from Flowey: "... ... Why?"

Trivia

• The Hydrochloric Acid cannot be dropped or sold.
• This is the same acid that is in a stomach. However, the stomach has a thick lining of mucus that protects you from getting digested like Clover did.
  • The mucus lining blushes when your face does.
