Why do weak acid-weak base reactions not go to completion?
There are not enough molecules in solution to react with each other.
The conjugate products are much weaker than the original acid and base.
Neither a weak acid nor a weak base has a strong tendency to transfer H+ ions.
Both weak acids and weak bases have a strong tendency to transfer H+ ions, so they cancel each other out.

I believe the answer is c @Abhisar

You are correct!!

can you explain it to me, so I understand?

eric_d · Answer

A weak acid is an acid that dissociates incompletely, releasing only some of its hydrogen atoms into the solution

anonymous · Answer

The thing that makes a weak acid weak is that it doesn't completely dissolve same goes for a weak base, so basically in a solution you'll have some ions in the solution and when you react that with a weak base or acid only those few ions will react.
