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 28.00 mL sample of 0.0300 M Ni2+ was added to 28.00 mL of 0.162 M iminodiacetic acid (the completely protonated form is abbreviated as H3A+) buffered at pH 7.00. Given that ?A2− is 4.6×10−3 at pH 7.00, what is the final concentration of Ni2+ remaining in solution?

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 32.50 mL sample of 0.0483 M Ni2+ was added to 32.50 mL of 0.198 M iminodiacetic acid (the completely protonated form is abbreviated as H3A+ ) buffered at pH 7.00. Given that ?A2− α A 2 − is 4.6×10−3 4.6...
