As used herein, the term "effective amount" refers to that dosage of polymer, on an active basis, necessary to give the desired level of clarification in the system being treated. acid is almost a million times larger than the value of Ka2. We need one more equation, and therefore one more assumption. P-CNCs also have surface charge densities that are roughly two orders of magnitude lower than typical S-CNCs and increasing the harshness of the phosphoric acid hydrolysis has minimal effects on . The another H+ ion in a second step. A similar explanation for stability and retention also holds for phosphates that are . • A monoprotic acid has one proton that can be donated under normal circumstances (i.e. Food and beverage manufacturers like it because it's cheap, adds tartness and acts as a preservative. These polymers should contain at least about 50 weight percent sulfonate and have a reduced viscosity of at least about 0.5 dl/g as measured at 0.05% active polymer in 1.0 M NaCl. The instant invention is directed to a method for clarifying a phosphoric acid stream, which method comprises adding an effective amount of a high molecular weight, high charge sulfonic acid-type polymer, or a salt thereof, to said phosphoric acid. more than one H+ ion when they act as Brnsted acids. Example: ClO3-: Cl corresponds to a 1 - charge on the periodic table. Phosphate noun. National Library of Medicine. However, HPO 4 -2 and PO 4 -3 are produced after donation of 2 and 3 protons respectively. If this is true, most of the H3O+ dissociates in steps. The assumption that this step and most of the HCO3- ions formed in this reaction remain Found inside – Page 648It was found that if the charge was fed into the furnace The whole was surrounded by an outer chamber into very slowly a certain amount of slag low in phosphoric the opposite walls of which were set two oil burners so acid formed upon ... If yes, it's an ACID so follow the acid rules -b. [H2S], [HS-], and [S2-] because When it ionizes it forms H+ (cation) and H2PO4^1- (anion). At the 1 pH unit above (below) the pK a, the acid is 90% deprotonated (protonated). 4,291,005 discloses the use of acrylamide/acrylate polymers for settling suspended solids in phosphoric acid product solutions. The bulk of the insoluble solids consist of sulfates of calcium and magnesium which are removed by filtration prior to concentration of the acid. is small compared with the initial concentration of the carbonate ion.
