6. In a double replacement reaction, positive ions are exchanged between two compounds. It typically occurs in ionic, aqueous solutions and often forms a precipitate, gas, or molecular
compound.
In a lab, silver nitrate and sodium chloride were reacted to demonstrate a double replacement
reaction. Both salts dissolved in water. Ions were exchanged between both compounds and
formed a precipitate.
Write a balanced chemical equation and predict the precipitate.
A. AgNO3(aq) + NaCl(aq) - AgCl(s) + NaNO3(aq)
B. 2AgNO3(aq) + NaCl(aq) + 2AgCl(s) + NaNO3(aq)
C. SNO3(aq) + NaCl(aq) → SCI(s) + NaNO3(aq)

D. 2SNO3(aq) + NaCl(aq) - 2SCI(s) + NaNO3(aq)
