<span>What
additional volume of 10.0 M HCl would be needed to exhaust the
remaining capacity of the buffer after the reaction described in Part B?
In other words, how much more of this HCl solution is required to
consume the remaining Tris in the buffer?
let x = how much more solution needed
x = 1.8 mL <=========
Your answer is 1.8 mL as it is needed for more of this HCI solution is requires to consume the remaining Tris in the buffer!
Have an awesome day! :D
