Webb9 sep. 2024 · K a of carbonic acid: 4.2 x 10 -7 concentration of carbonic acid: 0.035 mol/L (divided by 1.000 L to get concentration) concentration of hydrogen carbonate ion: 0.0035 mol/L We can use the acid dissociation constant equation to calculate hydronium ion concentration and then use -log [H 3 O +] to calculate the pH of buffer. Webb10 apr. 2012 · Ka is for the acid H-C6H5CO2, while Kb is for its conjugate base. You start with the conjugate base grabbing a H+ So you get C6H5CO2- + H2O -> OH- + HC6H5CO2 So your ice chart has to have Kb = x^2 / (conc of base) then convert the Ka to Kb and solve for X, and then solve for pOH, and then solve for pH 0 Buttafuoco Full Member …
