Net Ionic Equation, Silver nitrate and ammonium selenate net ionic equation
The net ionic equation is a simplified representation of a chemical reaction that shows only the ions that participate in the reaction. In the reaction between silver nitrate and ammonium selenate, the spectator ions are NH 4+and NO 3–, which do not participate in the reaction.
The net ionic equation is:
Ag++ 42-→ Ag 2 4(s)
Ion Exchange
The reaction between silver nitrate and ammonium selenate is an ion exchange reaction, in which the silver ions (Ag +) and selenate ions ( 42-) exchange places to form a new compound, silver selenate (Ag 2 4). The spectator ions, NH 4+and NO 3–, do not participate in the reaction and remain in solution.
Formation of Precipitate
The product of the reaction between silver nitrate and ammonium selenate is a solid precipitate of silver selenate (Ag 2 4). Silver selenate is a white, crystalline solid that is insoluble in water. The formation of the precipitate is due to the fact that the solubility product of silver selenate is very low, meaning that it is not very soluble in water.
