Academics

Two different compounds have the formulation CoBr(SO4).5 NH3. Compound A is dark violet, and compound B is red-violet. When compound A is treated with AgNO3(aq), no reaction occurs, whereas compound B reacts with AgNO3(aq) to form a white precipitate.When compound A is treated with BaCl2(aq), a white precipitate is formed, whereas compound B has no reaction with BaCl2(aq).

(a) Is Co in the same oxidation state in these complexes?

(b) Explain the reactivity of compounds A and B with AgNO3(aq) and BaCl2(aq).

(c) Are compounds A and B isomers of one another? If so, which category from Figure 23.19 best describes the isomerism observed for these complexes?

(d)Would compounds A and B be expected to be strong electrolytes, weak electrolytes, or nonelectrolytes?
