The predominate form equation

WebbPhosphate Buffers. Phosphoric acid is a triprotic acid which undergoes a stepwise dissociation as follows, where K 1 = 6.5 x 10 -3 ; K 2 = 6.2 x 10 -8 ; and K 3 = 3.6 x 10 -13 . Each of these three equilibrium equations can be expressed mathematically in several different ways. Taking the equation for K 2 as an example, each of the following is ... WebbAs a simple example, if the pH was 2.28, the ratio between the protonated and deprotonated form of the carboxyl group (pKa = 2.28) would be C O O X − C O O H = 10 X 0 = 1. This means [ C O O X −] = [ C O O H] and the …

WebbThe conjugate base form, In− (aq), is the predominant form of the indicator in the aqueous pH 7 buffer in beaker Y. This is because the pH is greater than the pKa of HIn, causing the equilibrium to form a significant amount of products, In− (aq) and H3O+ (aq). In beaker X the oil layer is yellow, whereas in beaker Y the oil layer is colorless. Webbstart with the equilibrium equation Keq = [leftA-] [HrightA] / ( [HleftA] [rightA-] ) rearrange and multiply top and bottom by [H+] Keq = ([leftA-][H+]/[HleftA]) * ([HrightA]/([rightA …
