**Problem 7: Equilibrium Concentration Calculation**

Calculate the equilibrium concentration of each aqueous species (\( \text{H}_2\text{A}, \text{HA}^-, \text{A}^{2-}, \text{H}_3\text{O}^+, \) and \( \text{OH}^- \)) in the solution. Assume a temperature of 25°C. For \( \text{H}_2\text{A} \), the \( \text{p}K_{a1} = 2.05 \) and \( \text{p}K_{a2} = 6.22 \).

a. \( 0.10 \, \text{M} \, \text{H}_2\text{A} \)

b. \( 0.10 \, \text{M} \, \text{Na}_2\text{A} \)

---

Note: Detailed calculations are required to determine the concentration of each species at equilibrium based on the given initial concentrations and \( \text{p}K_a \) values.
