Factors affecting TLC
In lab, you're having fun along with buffers based onto a 0.1 M solution of sodium phosphate at pH7.0. Into this system, there are three of pK A s as: 12.7, 7.21 and 2.12.
The known metal ion solution used contains 0.10 M of each of the six metal ions (i.e. 0.10 M Ag+ and 0.10M Pb2+). An equal volume of 3 M HCl and the known solution are mixed. What
