Here's the balanced chemical equation:
2 AgNO₃(aq) + FeSO₄(aq) → Ag₂SO₄(s) + Fe(NO₃)₂(aq)
Explanation:
* Reactants:
* Silver nitrate (AgNO₃) is a colorless, soluble ionic compound.
* Ferrous sulfate (FeSO₄) is a pale green, soluble ionic compound.
* Products:
* Silver sulfate (Ag₂SO₄) is a white, insoluble ionic compound that precipitates out of solution.
* Ferrous nitrate (Fe(NO₃)₂) is a soluble ionic compound that remains dissolved in solution.
Net Ionic Equation:
The net ionic equation shows only the species that are directly involved in the formation of the precipitate:
2 Ag⁺(aq) + SO₄²⁻(aq) → Ag₂SO₄(s)
Observations:
When you mix solutions of silver nitrate and ferrous sulfate, you will observe the following:
* Formation of a white precipitate: This is silver sulfate (Ag₂SO₄) which is insoluble in water.
* Solution color change: The solution will change from colorless to a light green color due to the formation of ferrous nitrate.
Uses:
This reaction can be used to:
* Synthesize silver sulfate: This compound is used in the production of silver halide photographic materials.
* Test for the presence of silver ions: The formation of a white precipitate indicates the presence of silver ions in the solution.
Note: This reaction is often carried out in a laboratory setting as a demonstration of precipitation reactions and the formation of insoluble compounds.
