Part B: Qualitative Analysis Anion Pre-Lab Report

 

Date____________ Name________________________________

Write and balance the Ion Exchange Reactions for the following steps in Part B: Use you Solubility Chart to predict the precipitates.

Step #16:

Calcium Nitrate (aq) + Sodium Biphosphate (aq)

 

 

 

 

 

 

Calcium Nitrate (aq) + Sodium Carbonate (aq) →

 

 

 

 

 

Step #19:

Calcium Carbonate (s) + Hydrochloric Acid (aq)

 

 

 

 

 

Step#20

Calcium Biphospahte (aq) + Ammonium Molybdate (aq)

 

 

Actual Equation is a REDOX. The acid converts biphosphate ion to dihydrogen phosphate which undergoes the following change:

 

H2PO41- + 12 MoO42- + 22 H3O1+ + 3 NH4 1+ <==> (NH4)3PO412MoO4 + 34 H2O

 

Step#21

Barium Nitrate (aq) + Sodium Sulfate (aq)

 

 

 

 

 

Step#23

Sodium Chloride (aq) + Silver Nitrate (aq)

 

 

 

 

 

Sodium Iodide (aq) + Silver Nitrate (aq)
