Kalcker alone have proved that 50% citric acid is NOT the correct ratio now. It's actually around 33%.
Maybe, who am I to say BUT I am pretty sure Kalcker did an equal 50/50 split when he mixed sodium chlorite and the citic acid together but if you say 33% then it must be true somewhere in some video -- how enlightening of you.
Even Jim did a 50/50 split -- anyway it seems like everyone wants to follow there own path and that is fine.
BUT remember -- I was just trying to keep it simple for the masses -- not for all you smart people.
Here's your enlightenment
The information starts at 14:00
Sorry, this video is in Spanish, because Kalcker was speaking at a conference in Spain (Yes, he speaks English, German and Spanish), so probably this information is still not available in other languages.
Enjoy the new research!
