The Sodium Chlorite flakes are 80% pure. The rest is mostly salt and some trace minerals. This is why you mix 28% flakes with 72% distilled water so you end up with 22.4% Sodium Chlorite Solution.

Mix: 280 grams of Sodium Chlorite Crystals

+

720 ml of distilled water. (If you would rather weigh the water for more accurate measurements 720 ml = 720 grams)

Caution: Do not use any metal in the making or storing of this solution.
