A coordination compound has been determined to be composed of 18.4% Co, 26.6% NH3, 30.0% SO4 , and 25.0% Br–, by mass. The compound was also determined to have two different isomers, A and B, such that the solution of isomer-A was found to react with AgNO3(aq) to produce AgBr precipitate, but the reaction with Ba(NO3)2(aq) did not produce any precipitate. While the solution of isomer-B did not produce any precipitate when reacted with AgNO3(aq), but it produced BaSO4 precipitated when the solution is reacted with Ba(NO3)2(aq). (a) Determine the empirical formula of the compound written in the form of Co(NH3)x(SO4)yBrz. (b) Assuming that all of NH3 molecules in the formula are ligands, deduce the Werner’s formula for isomers A and B, respectively, and give the systemic name for each isomer.(c) Write molecular equations for the reaction of each isomer with AgNO3(aq) and Ba(NO3)2(aq).
