Hello
A store that sells sodium chlorite sent me a chemistry

NaCl02 - 25,45%
NaCl03 - 0,22%
NaCl - 1,05%
NaOH - 0,21%
Na2CO3 - 0,45%
Na2SO4 - 0,1%
NaNO3 - 0,01%
As <3 PPM
Hg <0,1 PPM
Pb < 1 PPM

Is it ok?
Please help

Dear Ilia

It will work, but the chemistry does not make sense because if you add all the percentages up you do not get 100%
The sodium chlorite used most often is of 80% purity meaning
NaCl02 >= 80%

But yours will work fine, you might just have to compensate with the amounts used because yours is only 25%.
But before using be sure to ask the store what's in the 70% not listed.

Regards
Andrew

I believe that is a 25% solution she is referring to.

Thanks for answers!

Other ~70% is aqua.
It is aqueous solution of sodium chlorite.
80% purity?? - Is not it too dangerous, that other components have a high concentration of suspicious substance?
(or, i guess they are not too dangerous when they react with citric acid or something else...)

Oh no the other 20% is mostly sodium chloride (NaCl).
They make sodium chlorite by oxidising sodium chloride, so the 20% was just not oxidised.

Ok, NaCl is safety. It is good)
But, is my components safety?
(maybe they oxidised..)

Just for your curiosity these 3 are the ones that are harmful

As <3 PPM
Hg <0,1 PPM
Pb < 1 PPM

As you can see there is very little of them in your mix.
