Table of Acid and Base Strength Antidepressant Brain Fog Reddit, 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. .doc_ 1.7 x 10-5 NaC2H3O2 knowing that the pH is 9.1. also please Confirm or deny that the expression for the equilibrium constant derived from the Net ionic equation for hydrolysis is ( [HC2H3O2] [OH^-] ) / [C2H3O2] 2. 3. 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. >> Electrical Hazards Pdf, /FontDescriptor 7 0 R arrow_forward. >> /Leading 101 What time does normal church end on Sunday?
