Determine the relative volumes of conjugate base and weak acid that need to be taken from the respective stock solutions: (To avoid introducing rounding errors on intermediate calculations, enter your answer to four significant figures.) Total volume of buffer solution 1 L Buffer solution target pH 3.5 Stock (aq) concentration 0.100 M Stock (aq) concentration 0.300 M Show/Hide Help Previous HelpNext Help Help 1 of 5 Recall that you have a 0.100 M stock solution of the weak acid, and a 0.300 M stock solution of its conjugate base.
