If you prepare CDS by mixing solution of sodium chlorite and solution of hydrochloric acid. Pot in pot. The chlorine dioxide gas will evaporate from the mixture and gets absorbed by the water. I would like to achive 'some scientific level' on this topic.
At first, the mixture is in the wineglass is brown. After 30 min it is still brown, 12 hours later, it turns to the same colour as the CDS.
Do I get
pure CDS from this method?
Why does the brown completely disapear in the end?
What is the best quality? Is the 30 min beter than the 12 hours?
- ClO2 boiling point = 11 °C (11℃= 51.8℉)
- Hypochloric Acid boiling point = 48 ℃ = 118.4 ℉. The boiling point of Hypochloric Acid boiling point may be 48 ℃, but I guess that does not mean that no Hypochloric Acid will evaporate at lower temperatures. And I guess it is better that no Hypochloric Acid end up in the water.
I would even suggest the best way to make CDS, using this method, would be to do it just above the boiling point of CDS. That way, the lowest amount of Hypochloric Acid will end up in the water.
