Question

Predict whether a reaction will occur. If there is no reaction, write "no reaction". If there is a reaction, write the complete, complete ionic, and net ionic equations that describe the reaction. a. Aqueous ammonium chloride mixed with aqueous lead (II) phosphate b. Aqueous sodium hydroxide is mixed with aqueous iron (III) chloride c. Aqueous lithium iodide is mixes with aqueous barium sulfide Calculate the number of ions in each solution and rank from greatest number of ions to lowest number of ions. a. 400.0 mL of 1.50 M MgS. b. 300.0 mL of 1.00 M NaSO_4 c. 200.0 mL of 0.80 M Be_2(PO_4)_3

Explanation / Answer

(a)

Molecular equation:

6 NH4Cl (aq.) + Pb3(PO4)2 (aq.) ----------> 3 PbCl2 (s) + 2 (NH4)3PO4 (aq.)

Complete ionic equation:

6NH4+(aq.)+6Cl-(aq.)+3Pb2+(aq.)+2PO43-(aq.)----->3PbCl2(s)+6NH4+(aq.)+2PO43-(aq.)

Net ionic equation:

3 Pb2+ (aq.) + 6 Cl- (aq.) ------------> 3 PbCl2 (s)

(b)

Molecular equation:

3 NaOH (aq.) + FeCl3 (aq.) -----------> Fe(OH)3 (s) + 3 NaCl (aq.)

Complete ionic equation:

3 Na+ (aq.) + 3 OH- (aq.) + Fe3+ (aq.) + 3 Cl- (aq.) ---> Fe(OH)3 (s) + 3 Na+ (aq.) + 3 Cl- (aq.)

Net ionic equation:

Fe3+ (aq.) + 3 OH- (aq.) ----------> Fe(OH)3 (s)

(c)

Molecular equation:

2 LiI (aq.) + BaS (aq.) ------------> Li2S (aq.) + BaI2 (s)

Complete ionic equation:

2 Li+ (aq.) + 2 I- (aq.) + Ba2+ (aq.) + S2- (aq.) ---------> 2 Li+ (aq.) + S2- (aq.) + BaI2 (s)

Net ionic equation:

Ba2+ (aq.) + 2 I- (aq.) ----------> BaI2 (s)
