🧪 The Miraculous Water

Nitric, the key compound for freeing people from petrification in Dr. Stone.) *🌿 What is the Elixir of Depetrification?* The depetrification elixir is a chemical solution composed primarily of nitric acid (HNO₃), which reacts with the layer of stone covering petrified humans, breaking it down and restoring their bodies undamaged. This elixir is considered the key to reviving humanity and was one of Senku Ishigami's first major discoveries in the Stone World. *🔬 Composition and Formula of the Elixir* The elixir that Senku uses is based on the synthesis of Nitric Acid and Alcohol, achieving the reaction necessary to break the petrification. There are two versions of the elixir: Natural "Miracle Water": It is nitric acid that naturally seeps in certain places, such as the cave where Senku and Taiju found it. It is formed from the decomposition of guano (bat droppings) in damp, dark caves. It has a very low concentration and needs to be mixed with other compounds to be effective. Synthetic Elixir Created by Senku: Formula: Nitric Acid (HNO₃) + Alcohol (C₂H₅OH, ethanol) Creation process: Obtain potassium nitrate (KNO₃) from bird or bat droppings. Mix it with water and sulfuric acid (H₂SO₄) to obtain pure nitric acid. Add ethanol to complete the mixture and make it more effective. Why is platinum so important? Platinum is an essential catalyst for efficiently manufacturing nitric acid. Senku plans to use it to build a chemical reactor and produce nitric acid without the need for bat guano or primitive methods. This means that they will be able to revive all the petrified people without relying on the natural "Miracle Water". Scientific Process (Synthesis of Nitric Acid with Platinum): Ammonia (NH₃) is burned in the presence of a platinum catalyst. Nitric oxide (NO) is formed. reacting with h20 and air

⚡How does it work?

With a petrified person, an unknown chemical reaction occurs that breaks down the stone layer and regenerates any damage to the body. This process also heals wounds and rebuilds damaged organs, which is not possible in real chemistry and suggests that there is an advanced biological mechanism behind petrification. *⚠️ Limits and Effects of the Elixir* ✔ What you can do: Safely break the stone without harming the human body. Heals wounds, even regenerating lost organs (like Ukyo's voice). Revives anyone as long as their brain is intact. ❌ What you can't do: It does not revive people who have been completely destroyed in their stone state. It does not affect petrified animals or plants (it only works on humans). Its effectiveness depends on the amount applied and the concentration.
