netineya [11]

The precipitate that will be formed : AgF

<h3>Further explanation</h3>

One indication of the double displacement reaction is the precipitation reaction

Solubility Rules:  

• 1. soluble compound  

All compounds of Li +, Na +, K +, Rb +, Cs +, and NH4 +  

All compounds of NO₃⁻ and C₂H₃O₂⁻  

Compounds of Cl−, Br−, I− except Ag⁺, Hg₂²⁺, Pb²⁺  

Compounds of SO₄²⁻ except for Hg₂²⁺, Pb²⁺, Sr²⁺, Ba²⁺  

• 2. insoluble compounds  

Compounds of CO₃²⁻ and PO₄³⁻ except for Compounds of Li +, Na +, K +, Rb +, Cs +, and NH₄ +  

Compounds of OH− except Compounds of Li +, Na +, K +, Rb +, Cs +, NH₄⁺, Sr²⁺, and Ba²⁺  

Reaction

NaF(aq) + AgNO₃(aq) →NaNO₃(aq)+ AgF(s)

From the solubility rules above, it has been shown that the salts of the Ag⁺ cations are insoluble salts
