Dears,
I know this is very obvious question to most, but i am stuck in it and i appreciate your help.
I have been researching on formulating products that yields a predictable dose of oPO4, for example :
Having a product with 11% Phosphoric acid (85%), Should yield 9.1 ppm oPO4 , at 100ppm Conc. of the product.
How is this calculated, and what are the factors that increase and decrease the dissociation of phosphoric acid into oPO4?
