A solution contains 0.003Mof sodium phenobarbitaltogether with a buffer consisting of 0.20 M sodium acetateand 0.30 M acetic acid. Acetic acid is a weak electrolyte;its degree, or fraction, of dissociation, α, at thisconcentration is 0.008 and the undissociated species do notcontribute to the ionic strength. What is the ionic strength of thesolution?
pka for acetic acid = 4.8
