(For clarity, the sodium ions and water molecules are not shown.)(a) Which diagram corresponds to the beginning of the titration, prior to the addition of any NaOH?________________(c) Which diagram corresponds to the equivalence point of the titration? (Ignore salt hydrolysis.)________________(d) Which diagram illustrates the solution after the equivalence point, when excess NaOH has been added?________________(d) Which diagram corresponds to the point at which the pH is equal to the pKa of the weak acid?
