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

58750.08068 is the answer i think

10 years is the answer

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
