LAB DESCRIPTION: In aqueous solutions the Ni2+ cation forms a complex ion with 6 H2O ligands. The formula of this complex ion is: Ni(H2O)62+. When this complex ion is mixed with aqueous NH3 a reaction occurs where some of the H2O ligands are displaced with NH3 ligands. But how many of the H2O are displaced by NH3? In this experiment you will mix nickel(II) sulfate and aqueous ammonia to synthesize a compound containing a complex ion whose formula is Ni(H2O)6-x(NH3)x2+,...

1. A student obtained the following results from the spectroscopy and titration experiments: 26.80% en, 16.01% Ni2+, 26.20% SO4 2- , 30.99%H2O. Use this information to determine the empirical formula of the unknown complex nickel salt. (Remember that the calculations are based on data, so the mole ratios may not come out perfect…what should you do in this case?)
