the "antidote" with citric acid?

Hello, I know that you have a preference for HCl, sorry for being stubborn or insistent, but you have to imagine several situations and possibilities, plan A, plan B, ..., plan Z, as a range of options in the "survival". I imagine some very poor village, where they have no electricity, or also some developed place where there was a natural disaster or blackout, and they can not get muriatic acid from which to obtain HCl. They manage to get citric acid, but they have no electricity to refrigerate, the only viable thing would be the wonderful "the antidote" to use in the daytime, here the question is, can it be made with citric acid?
 

Yes, it can. As I recall use 35% citric acid.

I agree with your idea of being able to make CLO2 in an emergency situation. I have been working on what I will probably call "The MMS Survival Kit" which uses dry sodium chlorite flakes and dry citric acid to make CDS and CDH. One reason to use dry ingredients is the long shelf life; 20 years for SC flakes and at least 9 years for citric acid granules.

Here is one example:

   

After further testing, I suggest to use 4g SC flakes and 8g CA granules.
