What happens if you add .000009 mols of HCl to .004 mols of NaCl? What is the reaction occuring, and what would the theorhetical pH of that solution be?

HCl and NaOH neutralizes each other.

HCl (aq) + NaOH (aq) -> NaCl (aq) + H2O (l)

After neutralization, there's much NaOH left.

pH + POH = 14

POH =- log[OH-]

You should know volume of solution.
Then you can calculate concentration of OH-

Thank you but it's NaCl not NaOH. I'm confused because we're using the Lewis definition of acid - in this case Cl- is technically the acid becuase it's the "proton donor.".. I'm not sure how concentration of Cl- ions would affect pH when HCl is added.

You shoul need the volume of HCl.
You are right, Cl- have no influence to pH
