The pKb of a solution is defined by the equation: pKb= -logKb
where Kb= base dissociation constant.
Use the rules for logarithms and exponents to solve for Kb in terms of pKb

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.
