10 mL of an aqueous solution of HCI has a pH of 2.0. What volume of water must be added to this to raise the pH to 4.0? A buffer is prepared by adding 100 mL of 0.5 mol L¹ NaOH to 200 mL of 0.75 mol L¹ acetic acid (AcOH). What amount (mol) of HCI must be added to this buffer solution to change the pH by 0.14 units? If necessary, assume the total volume remains unchanged at 300 mL. 10 mL of an aqueous solution of HCI has a pH of 2.0. What volume of water must be added to this to raise the pH to 4.0?
