Write the net ionic equation for the following molecular equation. (Use the solubility rules provided in the OWL Preparation Page to determine the...

The balanced equation is:


    (aq) + (aq) -> (s) + (aq)


Solubility


We can determine the solubility of the compounds in this reaction two ways:


Use the state symbols:


  • The state symbol "aq" indicates that the substance is soluble in water. Therefore,  , and  are soluble in water. 
  • The state symbol "s" indicates that the substance is a solid that is not soluble in water. Therefore,   is not soluble...

Solubility


We can determine the solubility of the compounds in this reaction two ways:


Use the state symbols:


  • The state symbol "aq" indicates that the substance is soluble in water. Therefore,  , and  are soluble in water. 

  • The state symbol "s" indicates that the substance is a solid that is not soluble in water. Therefore,   is not soluble in water.

Use the solubility rules: 


  • "Nitrates: soluble ionic compounds" -  and  are soluble in water.

  • "Phosphates: insoluble except w/ sodium, potassium, or ammonium" -  is soluble in water,  is insoluble in water.

Net Ionic Equation


First, write the total ionic equation by separating all soluble substances into ions:


    + + + -> + +


Now, write the net ionic equation by removing all of the ions that are exactly the same on both sides of the equation:


    + ->
