No tracking or performance measurement cookies were served with this page. (Ex. Favorite Answer. /Filter /FlateDecode Solution : Ka*Kb = Kw Kb = Kw/Ka Ka of HC2H3O2 is 1.8*10^-5 So Kb = 1.0*10^-14 / 1.8*10^-5 Kb = 5.56*10^-10 So Kb value of HCO3- is 5.56*10^-10 Ka value f HCO3- is 5.6*10^-11 Kb = 1.0*10^-14 / 5.6*10^-11 Kb = 1.79*10^-4 So Kb value of CO3^2- is 1.79*10^-4, Posted Log in or register to post comments; Similar Questions. 2007-2021 Transweb Global Inc.

Terms The concentrations used in the equation for Ka are known as the equilibrium concentrations and can be determined by using an ICE table that lists the initial concentration, the change in concentration and the equilibrium concentration for H3O+, C2H3O2 and HC2H3O2. Solving for the Kb value is the same as the Ka value. I suspect you measured the pH of the solution, converted that to OH^- and plugged into Kb = (x)^2/C-x. 338 260 260 454 454 338 500 1000 300 867 434 270 868 338 338 603 arrow_forward. using the ka for hc2h3o2 and hco3 - ASE You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
