Stomach Acid Can Dissolve Metal – But Not Itself.
🔍 Fact: Human stomach acid is so strong (pH ~1.5) it can dissolve zinc and some other metals in lab conditions.
🧪 Why it matters: Your stomach protects itself from digesting its own tissue with a thick mucus lining that regenerates every few days. If this fails? You get ulcers.
