Hello all, i will try and make this short and sweet 

Ive read little bits here and there about phosphites, but i am unsure of how it is made. Ive read about people useing phosphorus acid and phosphoric acid in its manufactoring process. How is it made? At this point i can only guess. Is it the result of phosphoric or phosphorus acid meeting with rock phosphate?  Ive also read that an organic acid was used before in its manufactor.

Thank you for any help.
Brett
