Phthalic acid (H,C3H,O4, abbreviated H,Ph) is a diprotic acid. Its ionization in water at 25°C_takes place in two steps: H¿Ph(aq) + H20(e)=H;0* (aq) + HPH¯(aq) Ka1 = 1.26 × 10~³ %3D HPH¯(aq) + H,O(e)2H;0*(aq) + Ph² (aq) K22 3.10 × 10¬6 If 0.0100 mol of phthalic acid is dissolved per liter of water, calculate the equilibrium concentrations of H,Ph, HPH¯, Ph²-, and H;O*.
