how the hydrogen oxalate ion can be both a bronsted acid and a bronsted base
Barbituric acid (ka = 1.1x10^-4) is used in the manufacture of some sedatives. For a 0.6733 M solution of barbituric acid, calculate
Treating 1-butanol with sulfuric acid establishes an equilibrium with 1-butyl bisulfate and water as shown.
Calculate the [H3O+] concentration in 0.45 M solution of barbituric acid, HC4H3N2O3. Ka for barbituric acid is 1.0 X10 ^-5.
Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.
