19. I know H3PO4 is weak so it doesn't dissociate, so what I got was H3PO4 (aq) + OH^- (aq) -> 2H^+ (aq) + PO4^3- (aq) + H2O(l) But in my next question it asks to calculate the heat of the rxn for 1 mol of product, but in the Standard Enthalpies I can't find PO4, leading me to believe that I did something incorrectly. Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. any acid that is not one of the seven strong is a weak acid (e.g. H2BO3- H+ + Unlike a strong acid like HCl which dissociates in water to make H+ and Cl-, boric acid doesn't dissociate at all. First dissociation: H3PO4 (aq) H+ (aq) + H2PO4 - (aq) You calculate [H+] from this dissociation using the Ka equation which I am sure you know how to use.

[email protected], Details of the Affiliated University and Its Vice-Chancellor & Registrar, Details of the Principal & Medical Superintendent. To be acidic, hydrogen must be bound to a highly electronegative atom such as oxygen or fluorine. Since phosphoric acid, represented by the molecular formula H3PO4, has three hydrogen atoms, it dissociates three times, into H 2 PO 4 , HPO 4 2-and PO 4 3-.The pKa value is based on the Ka value, which is called the acid dissociation constant. By foss wild camp spot. Did Sally Die In Bloodline, ''Sometimes under presence of some acids like Concentrated Sulphuric acid, The disassociation stops to second or first reaction only.''
