4. Assume that a student places 1.0 mol of solid PbBr2 in 1.0 L of 0.0025 M Pb2+. Part of the lead bromide dissolves according to the following reaction PbBr2() + Pb²* (@q) + 2Br(aq) After allowing the solution to sit for 30 minutes the student determines that the bromide concentration was [Br] = 0.0010 M. What is the Pb2 concentration?
