Please note that you should have ∗total∗ respect for
the chlorite family of compounds:

> NaCl0 sodium hypochlorite

This is laundry bleach. Dangerous, but workable if you
respect it.

> NaCl02 sodium chlorite

Used in industrial processes, as a microcide and as a
pesticide. More nasty/dangerous. Take nothing for
granted and always follow a carefully planned
handeling routine. Never deviate from the routine.

> NaCl03 sodium chlorate

Used in industrial processes (Mainly the manufacture
of paper) and as a herbacide. Nasty and dangerous. I
don't want around me or at my house/business.

> Na(Cl0) sodium perchlorate

Strong oxidizer and unstable. Spontaneous combustion
is possible. Don't drop it, it will probably explode.
Heat sensitive. As I recall, it's hygroscopic. Totally
nasty/dangerous. This stuff falls into my "I don't
want no parts of this sh!t" catagory.

Marvin Dickens
