Iodite anion

[edit]

Iodites (including iodous acid) are highly unstable and have been observed[1] but never isolated.[citation needed] They will rapidly disproportionate to molecular Iodine and Iodates.[2] However, they have been detected as intermediates in the conversion between iodide and iodate.[3][4]

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
