Practice Problems on Net Ionic Equations:
Show the total ionic and net ionic forms of the following equations. If all species are spectator ions, please indicate 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)
2. Mg(NO3)2 (aq) + Na2CO3 (aq) ® MgCO3 (s) + NaNO3 (aq)
3. strontium bromide (aq) + potassium sulfate (aq) ® strontium sulfate (s) +
potassium bromide (aq)
4. manganese(II) chloride (aq) + ammonium carbonate (aq) ® manganese(II) carbonate (s)
+ ammonium chloride (aq)
5. chromium(III) nitrate (aq) + iron(II) sulfate (aq) ® chromium(III) sulfate (aq) +
iron(II) nitrate (aq)
