The mixing of which pair of reactants will result in a precipitation reaction? A. Ba(NO3)2(aq) + Na2CO3(aq) B. NH4Br(aq) + NH4I(
Semenov [28]

Answer:

A. Ba(NO₃)₂(aq) + Na₂CO₃(aq)

Explanation:

  • The reaction between aqueous Ba(NO₃)₂ and Na₂CO₃ is a precipitation reaction.
  • The complete equation for the reaction is;

Ba(NO₃)₂(aq) + Na₂CO₃(aq) → BaCO₃(s) + NaNO₃(aq)

  • Barium carbonate is the precipitate formed during the reaction.
  • All nitrates are soluble in water and all salts of sodium are soluble in water, therefore, Ba(NO₃)₂, Na₂CO3, and NaNO₃ are soluble in water.
  • Precipitation reaction involves reaction of soluble salts to form a precipitate as one of the product.
