Suppose I had an acid HA, and it reaches equilibrium in water. Then I remove the hydronium ions. I don't know how I would do this, maybe adding some hydroxide ions. My question is can I do this and will I be able to eventually create a 50/50 mixture of acid and conjugate base? Is this a very good buffer?

$\begingroup$ The quick answer is that it depends what 'A' is. $\endgroup$ – jerepierre Mar 10 '15 at 17:45

You can't just remove hydronium ions because the solution needs to remain electrically neutral.
You can't just add hydroxide ions, but you could add sodium hydroxide until the HA/A- ratio was 50/50.
Is this a very good buffer?
It is the optimum ratio of HA and A- for buffering.
