Iminodiacetic acid (IDA) is often used in ion exchange resins as a way to remove heavy metals from industrial waste waters. It forms a 2:1 complex with many heavy metals, with a high selectivity for divalent over monovalent ions. A 10.50 ml. sample of 0.0582 M Ni2+ was added to 10.50 mL of 0.169 M iminodiacetic acid (the completely protonated form is abbreviated as H, A*) buffered at pH 7.00. Given that a is 4.6 x 10- at pH 7.00, what is the final concentration of Ni* remaining in solution? Ni (aq) + 2 A?-(aq) = NiA? (aq) K = 2.00 x 104
