Question

What volume (mL) of 0.20 M HCl needs to be added to 1.23 L of 0.10 M acetic acid to reduce the percent ionization to 1.00%? Assume the volume of HCl added is negligible compared to the volume of the whole solution, and that the small x
approximation is valid.

Answer 1

I worked this for you last night and added an addendum to it this morning. I assume you've not looked for it. If you have some questions about it or the solution to it, repost it along with whatever solution and/or questions you have.
