**Title: Calculating the pH of a Maleic Acid Solution during Titration**

A 100.0 mL solution containing 0.790 g of maleic acid (MW = 116.072 g/mol) is titrated with 0.284 M KOH. Calculate the pH of the solution after the addition of 48.0 mL of the KOH solution. Maleic acid has \( pK_a \) values of 1.92 and 6.27.

\[ \text{pH} = \]

---

**Concentration of Maleic Acid Forms at Equilibrium**

At this pH, calculate the concentration of each form of maleic acid in the solution at equilibrium. The three forms of maleic acid are abbreviated as \( H_2M \), \( HM^- \), and \( M^{2-} \), which represent the fully protonated, intermediate, and fully deprotonated forms, respectively.

\[ [M^{2-}] = \quad \text{M} \]

\[ [HM^-] = \quad \text{M} \]

\[ [H_2M] = \quad \text{M} \]

**Note**: Use the provided tools for \(\times10^{y}\) for adjusting concentration scales.
