20 P)A1 L buffer solution contains 30 mmol NaHSO3 and 90 mmol Na2SO3.Let's assume
that we run out of materials to prepare this bumper.We have Na2CO3k),Na.HPO4(k),1M
dimethylamine,NaOH(k)and 1M HNO3.Prepare a buffer solution with the same pH as the
NaHSO3-Na2SO3 buffer using the ones you need from these materials.
