Question

A certain weak base has a Kb of 8.00

Answer 1

Given pH = 10.26

WE know that pH + pOH = 14

So pOH = 14 - pH

            = 14 - 10.26

           = 3.74

pOH = - log[OH^- ] = 3.74

                [OH^- ] = 10 ^-3.74 = 1.82x10 ^-4 M

Now we know that                     c = concentration = ?

                                                

                      

concentration of this base is 0.04 M
