Consider a solution that is 0.10 M in a weak triprotic acid (A triprotic acid is an acid which has three H, or hydrogen, atoms )which is represented by the general formula H3A with the given ionization constants: K1 = 1.0×10-3, K2 = 1.0×10-8,,K3 = 1.0 × 10-12. Determine which species is present in the lowest concentration in 0.10 M H3A solution?
