Can you have a basic solution with an acid and its salt?

Suppose you had an acid with a very high pKa and therefore a very low Ka. And you put the conjugate base in (via a salt). The conjugate base wil force the hydronium concentration very low (much lower than it already was). Is it possible for it to force the concentration below 10^-7 for a basic pH?

You mean like the acid Methane and then adding its conjugate base via Sodium Methide?

Or add the acid Water, and then add its conjugate base via Sodium Hydroxide?

Remember, everything is an acid, if you pull on its protons hard enough.

I'm not sure what you're talking about. An "acid" with a very high pKa wouldn't really be an acid - it would just exist in the protonated state over a wide pH range. If you then add the conjugate base in and the pH is still <pKa, then that conjugate base form will want to exist as the protonated state and therefore will become protonated. Those protons will come from the solution and you're just making the solution more basic. Which is the effect of adding any base to a solution.
