Difference between Sodium Chlorite and Sodium Chlorite Puriss P.A.

Hi
There is any difference between "Normal" Sodium Chlorite at 28% or I MUST use Puriss P.A. product ?

The Chlorate in industry Sodium Chlorite can be dismiss by using CDS protocol?

Thanks in advance

havent' any idea what the sodium chlorite puriss p.a. is - do you have a link?

Hi Pam. Sure, look this...

According some people here in Brazil, there is a difference. The "normal" or industrial Chlorite has Chlorates on its composition what becomes it not pure. The puriss P.A. is free of Chlorates, because of this its pure and more expensive, R$ 328,00 and R$ 417,00 respectively.

I don't know - will be honest - Jim has never differentiated, therefore I would assume that this is an advertising gimmick.

Humm! Can be. I will go to ask people at Chemistry College in my town. If I have solid information, I´ll post here.

Check to see how much Puriss P.A. has contributed to the chemistry department, while you are at it, LOL.

In chemistry we have different grades of purity. For lab test have to be High purity because we are determining concentration. But for prepared solution we can accept reagent grade that can have some grade of impurities. In the case of NaCl02 due to the high risk of Explosion is always ship with some salt added to avoid problem. That amount of high purity probably is just a little amount of grams like 10 grams. But for this forum and everybody using MMS should be 80% of purity.

Hi giplacres! So if I right understand, there is a real difference between them. I´m dealing with a company in China and I was confused about it. The RT, grade, concentration or solution are the same thing? So concentration of 80% is same as purity as 80%?

Yes, that what they mean. And is that way because is difficult to produce big amount at 99.99% it will explode.

So 28% of solution recommended by Jim Humble means 28 parts of NaClO2 and 72 parts of diluent?
