Calculating the Kb of a Weak Salt
Assume the starting concentration of NaHCO3 is 0.100M
First calculate the [H3O+]
we assume the NaCl pH indicates the
concentration of [H3O+] in boiled water
this will be initial [OH-]
this will be final [OH-]
Set Up the ICE table
Calculate the value for x
because [OH-]final = [OH-]initial + x
so x = [OH-]final - [OH-]initial
Determine the Kb
