EXPERIMENT 8: REPORT FORM Reactions in Aqueous Solution - Double Displacement Reactions Date: Name Instructor: 1. barium chloride (aq) + sodium sulfate (aq) Balanced Formula Equation Complete lonic Equation: Net Ionic Equation 2, silver nitrate (aq) + sodium chloride (aq) Observation: Balanced Formula Equation: Complete lonic Equation: Net lonic Equation 3. lead(II) nitrate (aq) + potassium iodide (aq) Observation Complete Ionic Equation Net Ionic Equation CHEM 1411 Esperiment 8 | Reactions in Aqueous Solution 83

Explanation / Answer

1)

observation: white precipitate of BaSO4 is formed.

Balanced formula equation :

BaCl2 + Na2SO4 ------> BaSO4 + 2NaCl

Complete ionic eqution:

Ba2+ + Cl- + Na+ +SO42- -----------> Na+ + Cl- + BaSO4

As BaSO4 is water insoluble, it is not written in the form of ions.

Net ionic equation:

Ba2+ + SO42- -----------> BaSO4

As Cl- and Na+ cancel out from reactant side and product side.
