When each of the following aqueous solutions is mixed, does a precipitation reaction occur? If so, write balanced molecular, total ionic, and net ionic equations (enter the sum of the coefficients for the net ionic equation, remember coefficients of 1; if no precipitation reaction occurs write none):

1. potassium carbonate + barium hydroxide

2. silver nitrate + sodium sulfate

3. lead(II) nitrate + potassium bromide

4. sodium chloride + magnesium iodide

Expert Solution

1. potassium carbonate + barium hydroxide

precipitate forms - BaCO3

balanced : K2CO3 (aq) + Ba(OH)2 (aq) ------------> BaCO3 (s) + 2 KOH (aq)

total ionic : 2 K+ (aq) + CO32- (aq) + Ba+2 (aq) + 2 OH- (aq) ------------> BaCO3 (s) + 2 K+ (aq) + 2 OH- (aq)

net ionic : Ba+2 (aq) + CO32- (aq) --------------> BaCO3 (s)

2. silver nitrate + sodium sulfate

precipitate forms - Ag2SO4

balanced : 2 AgNO3 (aq) + Na2SO4 (aq) ---------------> Ag2SO4 (s) + 2 NaNO3 (aq)

total ionic : 2 Ag+ (aq) + 2 NO3- (aq) + 2 Na+ (aq) + SO42- (aq) -----------> Ag2SO4 (s) +2 Na+ (aq)+2 NO3- (aq)

net ionic : 2 Ag+ (aq) + SO42- (aq) -----------> Ag2SO4 (s)

3. lead(II) nitrate + potassium bromide

balanced : Pb(NO3)2 (aq) + 2 KBr (aq) -------------> PbBr2 (s) + 2 KNO3 (aq)

total ionic : Pb+2 (aq) + 2 NO3- (aq)+ 2 K+ (aq)+ 2 Br- (aq) -------------> PbBr2 (s) + 2 K+ (aq) + 2 NO3- (aq)

net ionic : Pb+2 (aq) + 2 Br- (aq) -------------> PbBr2 (s)

4. sodium chloride + magnesium iodide

no precipite forms
