Guest guest Posted March 6, 2010 Report Share Posted March 6, 2010 Hello Tom, You are explaining very well. Thank You. So it is possible to conclude that one drop of 5% chlorine dioxide solution mixed with one drop of 10% citric acid, would be much safer and efficient. That would be the whole idea behind MMS5 at 1:1. Do I understand correctly? Arie From: silverfox_science <poast@...>Subject: [ ] Re: More answers from Tom Date: Saturday, March 6, 2010, 1:24 AM Hello Arie,The amount of chlorine dioxide released from sodium chlorite depends on how low you drop the PH of the solution. At a PH of 3.5, only about 10% of the available chlorine dioxide is released as free chlorine dioxide.I have no idea why Jim Humble thinks a 5:1 ratio is needed with citric acid. Perhaps he is worried about the strength of the 28% solution and is diluting the dose with extra citric acid. You will have to ask him about this.I do know that a 1:1 ratio is more effective with 10% citric acid, and you don't contaminate the solution with extra citric acid. Since many people can be somewhat sensitive to citric acid, I would think that the least amount needed to get the job done would be the best amount to use.I think the real reason is that Jim started off using apple cider vinegar for activation. Since no one in industry uses that activator, I don't know if a 1:1 ratio would work as well as his 5:1 ratio. There is a difference in the strength of the acid. Vinegar is about 5% whereas the citric acid solution is 10%.Often in industry a 50% citric acid solution is used with the ratio of 5 parts sodium chlorite to 1 part 50% citric acid. Perhaps this brought some confusion... I don't know.Tom>> Hello Tom,> Â > OK I understand your point.> But is 1 drop of citric acid enough to release the necessary amount of chlorine dioxide?> Otherwise why would Jim insist on a 1:5 ratio?> Â > Thank you for your patience.> Â > Arie Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 6, 2010 Report Share Posted March 6, 2010 Hello Arie, The safety aspect has to do with the concentration of sodium chlorite. A 5% sodium chlorite solution is much safer to handle than a solution with a higher concentration. For example: If you happen to spill some 5% sodium chlorite, you can simply wipe it up. However, with a higher concentration solution, special steps have to be taken to prevent further problems. Chlorine dioxide can be generated from either a low concentration sodium chlorite solution or a high concentration sodium chlorite solution. To generate the same amount of chlorine dioxide you have to use more of the low concentration sodium chlorite solution than you would the high concentration sodium chlorite solution. When using 10% citric acid to activate sodium chlorite solutions the most effective ratio to use is 1:1.
