1) AgNO3 + K3PO4→

The reaction between silver nitrate (AgNO3) and potassium phosphate (K3PO4) is a double displacement (or metathesis) reaction. In this reaction, the silver ions (Ag⁺) and the potassium ions (K⁺) exchange partners, resulting in the formation of silver phosphate (Ag3PO4) and potassium nitrate (KNO3).

The balanced equation for the reaction is:

\[ 3 \, \text{AgNO}_3 + \text{K}_3\text{PO}_4 \rightarrow \text{Ag}_3\text{PO}_4 + 3 \, \text{KNO}_3 \]

In this equation:

• 3 moles of silver nitrate react with 1 mole of potassium phosphate to produce 1 mole of silver phosphate and 3 moles of potassium nitrate.
• Silver phosphate (Ag3PO4) is not very soluble in water, and it will precipitate out of the solution.
