Will a precipitate (ppt) form when 300. mL of 5.0 * 10^-5 M AgNO₃ are added to 200. mL of 2.5 * 10^-7 M NaBr? Answer yes or no, and identify the precipitate if there is one.

Quizplus · Accepted Answer

When AgNO3 and NaBr are mixed, Ag+ ions react with Br- ions to form a precipitate of AgBr. The balanced chemical equation for the reaction is:
AgNO3(aq) + NaBr(aq) → AgBr(s) + NaNO3(aq)
Since AgBr is insoluble in water, it will precipitate out of the solution, indicating that a precipitate will form. Therefore, the best choice is B, which states that the ppt is AgBr(s).
