FREE Expert Solution

We are being asked to determine if a precipitate will form from for the given mixtures:


I. 100. mL of 0.06 M Pb(NO3)2 and 50.0 mL of 0.03 M NaBr

II. 100. mL of 0.08 M Pb(NO3)2 and 100.0 mL of 0.05 M NaBr


For this problem, follow these steps:

Step 1. Determine the molarity of each ion involved in the precipitate (Pb2+ and Br-) via dilution

Step 2.. Calculate for Q (reaction quotient) and determine if a precipitate will form.
