Topical Questions
These questions are keyed to the major topics in the chapter. Usually a question that is answered at the back of this book is paired with a similar one that is not.
For each of these pairs of ionic compounds, write a balanced equation reflecting whether precipitation will occur in aqueous solution. For those combinations that do not produce a precipitate, write “NP.”
(a) HNO3 + Na3PO4
(b) NaCl + Pb(CH3COO)2
(c) (NH4)2S + NiCl2
(d) K2SO4 + Cu(NO3)2
(e) FeCl3 + NaOH
(f ) AgNO3 + KCl
