A biochemist prepared a 0.10 M solution of imidazole/imidazolium ions to buffer a reaction. The reaction within this buffered solution produced 0.006 M OH- ions. To the nearest hundredth, what will be the final pH of this buffered solution if the initial pH (i.e., the pH prior to the reaction producing the OH- ions) was 6.48? The pKa of the imidazolium ion is 6.0.
