Project for the 5th period.

I Practice Problems on Net Ionic Equations:

a. Show the total ionic and net ionic forms of the following equations. If all species are spectator ions, pleaseindicate that no reaction takes place. Note! You need to make sure the original equation is balanced before proceeding! A set of solubility rules are given at the end of this document.

1. AgNO3(aq) + KCl (aq) AgCl (s) + KNO3 (aq)

Total ionic:
Ag+ (aq) + NO3 ̄ (aq) + K+ (aq) + Cl ̄ (aq) --> AgCl (s) + K+ (aq) + NO3 ̄ (aq)
Net ionic:
Ag+ (aq) + Cl ̄ (aq) --> AgCl(s)

2. strontium bromide (aq) + potassium sulfate (aq) strontium sulfate (s) +

potassium bromide (aq)
Total Ionic:
Sr2+ (aq) + 2 Br ̄ (aq) + 2 K+ (aq) + SO42- (aq) --> SrSO4(s) + 2 K+ (aq) + 2 Br ̄ (aq)
Net Ionic:
Sr2+ (aq) + SO42- (aq) --> SrSO4 (s)
Molecular:
SrBr2 (aq) + K2SO4 (aq) --> SrSO4 (s) + 2 KBr (aq)

3. manganese(II) chloride (aq) +ammonium carbonate (aq) manganese(II) carbonate (s)

+ ammonium chloride (aq)
Total Ionic:
Mn2+ (aq) + 2 Cl ̄ (aq) + 2 NH4+ (aq) + CO32- (aq) --> MnCO3 (s) + 2 NH4+ (aq) + 2 Cl ̄ (aq)Net Ionic:
Mn2+ (aq) + CO32- (aq) --> MnCO3 (s)
Molecular:
MnCl2 (aq) + (NH4)2CO3 (aq) --> MnCO3 (s) + 2 NH4Cl (aq)

b. Please complete the following reactions, and show the completeionic and net ionic forms of the equation:

4. K3PO4 (aq) + Al(NO3)3 (aq) AlPO4 (s) + 3 KNO3 (aq)

Total Ionic:
3 K+ (aq) + PO43- (aq) + Al3+ (aq) + 3 NO3 ̄ (aq) -- > AlPO4 (s) + 3 K+(aq) 3NO3 ̄ (aq)

Net Ionic:
Al3+ (aq) + PO43- (aq) --> AlPO4 (s)

5. BeI2 (aq) + Cu2SO4 (aq) BeSO4 (aq) + 2 CuI (s)

Total Ionic:
Be2+ (aq) + 2 I ̄ (aq) 2 Cu+ (aq) + SO42- (aq)--> Be2+ (aq) + SO42- (aq) + 2 CuI (s)

Net Ionic:
2 Cu2+ (aq) + 2 I ̄ (aq) --> 2 CuI (s)
