Reply	mmmm says: I am no chemist, but I think it only applies to elemental potassium, and just because it is so willing to react it doesn't really occur in nature in elemental form, but in ionic salts where it is already oxidized.  (no votes) Tags: stomach, banana, Acids, alkalis.

Possibly as KCl or the salt of an organic anion. Look at it this way. Pottassium is so reactive, that it already reacted with something in the banana and formed a very stable potassium salt. So it doesn't react with HCl in the stomach.   This stands for all other metals that the body requires, I believe. They do not come in elemental form.   (no votes) Tags: stomach, banana, Acids, alkalis. posted on 2009-10-08 16:34:11 | Report abuse

Reply	JosephM says: This question reminds me of one about how water can put out fires. As we all know water is made from oxygen, rather flammable, and hydrogen, even more flammable. Their flammable properties only occur when in elemental form. It is all to do with the bonding of substances.
