Oh my, you've not made many friends here today, but then, I suppose that was your point.
You are woefully confused about what ClO2 is, which means, basically, you should either learn about it, or quite arguing with people who can disprove your "knowledge" immediately.
You were very nasty to Catlin, not nice. We don't like that here. If you dare to come back, you better spend some time with Miss Manners first.
So, just for you, here are some of the basics, although it's up to whether or not you want to keep on looking silly.
You want chlorine and chlorine dioxide to both have the qualities of "chlorine" but you don't clarify what you're talking about. Are you talking about the chlorine atom, i.e. Cl, or the gaseous form, Cl2, or what? Do you know the difference between an atom and a molecule?
Do you know that chlorine doesn't exist on it's own in nature? Most commonly, it's made through the seperation of NaCl, which is a salt. Found in the oceans. Is that just like ClO2, too? Salt?
Here are just a few of the different compounds containing "chlorine" as in the atom cl:
I also thought that your claim that ClO2 and Cl or Cl2 (I don't know which) behave the same way because they're both "chlorine," i.e. kill bacteria, funny for another reason. The following is from another site in which our first poster tries to convince others that there is no chlorine in ClO2. Your anti-claim, which leads to the same silly conclusion.
"There is no chlorine (Cl2) in chlorine dioxide (ClO2). Although chlorine dioxide has the word chlorine in its name, the two chemicals have completely different chemical structures. The additional oxygen atom radically changes the molecule and creates completely different chemical behaviors and by-products."
Then, this is followed up by a person who went to one of those, what are they, those colleges you spoke on, golly, says you can call him doc (I wonder if he/she knows what semantics are, hmmm).
"First, the terminology is jumbled. Any compound containing the element chlorine (atomic symbol Cl)
does, tautologically, contain chlorine. Molecular chlorine (Cl2) is a gas, and is obviously a completely
different molecule from ClO2. This however has no bearing on the properties of ClO2, and certainly does
not demonstrate that ClO2 is innocuous."
So, you may be able to see into the year 2029, you might want to read a little about ClO2 for now. Or not....
