Oops, I mean the molarity would decrease because moles base / larger quantity in L = a small # therefore decreased molarity. Correct?

How will overshooting the end point of an acid-base titration by adding too much base to KHP affect the calculated molarity of the base? I would think you would need to add more KHP, then more base to bring it to the endpoint. So the molarity calculated should be the same. Is ...

So, Mols NaOH = 0.2264 M NaOH x 0.04936 L NaOH = 0.011175 Mols KHP = grams KHP / molar mass KHP or grams KHP = Mols KHP x molar mass KHP so 0.011175 x 204.22 = 2.2822 grams of KHP Is that correct DBob222?
