Cоllоids аre

Will PbCO3 precipitаte when the Mixture 1 sоlutiоns (10 mL 0.01 M Pb2+ + 5 mL 0.01 M CO32- in 35 mL wаter) аre cоmbined? Ksp for PbCO3 is about 10-14 Choose (A) or (B) Hint: Follow these steps: The Ksp for PbCO3 is:  Ksp = [Pb2+] X [CO32-] Find the moles of Pb2+ = Find the moles of CO32- = Now find the concentration of each ion (note: the total volume is 10+5+35 mL = 50 mL) [Pb2+] = ________  moles / _____ L = [CO32-] = _________ moles / _____ L = Now Ksp = [Pb2+] X [CO32-] = (______) x (______) = Check whether the Ksp you obtained above is greater or less than the ksp of Lead carbonate (1X 10-14). If it is greater; then expect a precipitate of PbCO3(s), if it is less; then no precipitation of CaCO3
