A 0.4-L unbuffered solution needs the pH adjusted from 10.0 to 3.0. How many microliters of a 7 molar HCl solution need to be added to adjust the pH? Report your answer to four decimal places. For this question: Assume the volume of HCl being added is negligible and the total volume of the solution does not change. The volume of the solution is *not* 1 L like it was in the practice pools. The question requests your answer be reported in µL (microliters)!!
