Acid in our stomach is so powerful- It can dissolve razor blades
The acid in our stomach that is HCl hydrochloric acid ( pH 2) is so powerful that it can even dissolve razor blades. Of course, we are not supposed to actually get razor blades in our body, but this is just to indicate how strong your body acids are, if they can dissolve something like metal.
Food for thought:
If it is too powerful then how does it not harm the cells in the stomach?
Well, the cells in the lining of the stomach regenerate so rapidly that HCl does not get enough time to destroy them (The intestinal epithelium is replenished every 3–4 days through an orderly process that maintains important secretory and absorptive functions while preserving a continuous mucosal barrier).
Stomach acid’s low pH level is largely attributable to one ingredient: Hydrochloric acid (HCl). Other components include Potassium chloride (KCl) and Sodium chloride (NaCl).
The cells lining our stomach wall secrete this acidic trio. The cells also release several enzymes and mucus. This mucus is vitally important to the process. It protects the lining of your stomach so the acid and other gastric juices don’t damage the sensitive organs.
Scientists have experimented with razor blades, disk batteries and capsules by putting them in an acid-simulating juice to see how best to deal with them if swallowed accidentally. The researchers found that 24 hours later, razor blades lost their original weight and became 63 % Of its weight, and became fragile. Forget what they say about swallowing a seed and having a tree grow inside you. The Ph level in the stomach ranges from 1-3 which is so strong a mere seed cannot hope to survive.
