In an acid-base neutralization titration, where the end point is a neutral solution, the unknown concentration of the receiving solution can be calculated because...

- the concentration of he acid solution must match the concentration of the basic solution

- the volume of the acidic solution must match the volume of the basic solution

- moles of H3O+ ions donated by the acid must match the moles of the OH- ions donated by the base

- volume of the titrant must be half of the solution formed from the titration

Please explain the answer, I'm very confused T^T
Thank you all so much!
