Which of the following double-replacement reactions will occur? NaBr(aq) + AgNO3(aq) →

NaBr(aq) + Ca(NO3)2(aq) →

NaBr(aq) + Al(NO3)2(aq) →

NaBr(aq) + KNO3(aq) →

NaBr(aq) + AgNO3(aq) →NaNO3(aq) + AgBr(s)⇒ double-replacement reactions will occur

Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

A double replacement reaction will occur if one or both of the products is an insoluble precipitate, a liquid, or a gas

To predict whether this reaction can occur or not is one of them, the precipitation reaction. A precipitation reaction occurs if two ionic compounds which are dissolved reacted to produce one of the products of the ion compound does not dissolve. Formation of these precipitating compounds that cause reactions can occur

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 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⁺

NaBr(aq) + AgNO3(aq) →NaNO3(aq) + AgBr(s)⇒ occur

NaBr(aq) + Ca(NO3)2(aq) → NaNO3(aq) + CaBr₂(aq)⇒not occur

NaBr(aq) + Al(NO3)3(aq) →NaNO3(aq) + AlBr3(aq)⇒not occur

NaBr(aq) + KNO3(aq) →NaNO3(aq) + KBr(aq)⇒not occur
