Question about chemestry in SN

[bodrioirredento]

I found a seller of SN and i asked for the security sheet of the product

The description says SN anhydrous in granular form.

the purity is from 90% to 100%

solubility 820gr. per lt, or 82 %

But the formula is different i know that the formula is NaNO2 but in their description says NNaO2 will this affect the purposes of the SN, its the same?

it will work?

 

[aminend]

NNaO2 is same NaNO2, but the purity must be over 95%

Th

NNaO2 is same NaNO2, but the purity must be over 95%

Thank you for your answer, but the purity varies from 90 to 100 according to the safety sheet.
in this case i should ingest more? for example 35 gr. of SN? it will work?
