Quick question, in December 2020 I bought 1kg of repackaged KNO3 supposedly intended for agricultural uses. KNO3 is a controlled substance here and unavailable for the general population, so these second hand packages are the only choice I found. The salesperson called it 100% pure for agricultural standards, whatever that means.
Having used roughly half the package, I noticed that the powder is now getting yellow, just like an old book. Is it OK to keep using it, or should I look for a new batch?
