A 0.1-L unbuffered solution needs the pH adjusted from 6.8 to 2. How many microliters of a 6 molar HCI solution need to be added to adjust the pH? Report your answer to four decimal places. For this question: • Assume the volume of HCI 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 uL (microliters)!

Each row of the table below describes an aqueous solution at 25 °C. The second column of the table shows the initial components of the solution. • Use the checkboxes in the third column to explain the type of the initial solution. The fourth column describes a change in the solution. • Use the fifth column to predict how the change in the solution will change its pH. alo initial type solution initial components (check all that apply) effect of change on pH change (check one) O acidic pH higher H,0 basic add H C10, O pH lower A O neutral O pH the same acidic O pH higher H,0 add Na ClO, B O basic O pH lower O neutral pH the same O acidic pH higher Н, 0, КОН V basic add H Br O pH lower O neutral O pH the same O acidic O pH higher D Н,о, КОН O basic add K Br O pH lower O neutral pH the same Explanation Check © 2021 McGraw Hill LLC.
