(25pts) A liquid-liquid extraction process conducted in Electrochemical Materials Laboratory involved the extraction of nickel from the aqueous phase into an organic phase. A typical set of experimental data from the laboratory is given below. 1.50 2.50 3.00 Ni aqueous phase a(g/l) Ni organic phase 6.37 10.0 12.0 Assuming g is the amount of Ni in the organic phase and a is the amount of Ni in the aqueous phase, the quadratic interpolant that estimates g is given by g=x, a + x2a +xz Estimate the amount of nickel in the organic phase when 2.3g/l is in the aqueous phase using the quadratic formula.
