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 47.00 ml sample of 0.0724 m ni2+ was added to 47.00 ml of 0.179 m iminodiacetic acid (the completely protonated form is abbreviated as h3at) buffered at ph 7.00. given that α 2 is 4.6 x 10-3 at ph 7.00, what is the final concentration of ni2+ remaining in solution? ni2+ (aq) +2a2-(aq) 근 nia|-(aq) k,-2.00 x 1014 number m ni
