Dilution question in many of the experiments, you will be asked to prepare a standard solution by diluting a stock solution. you will be specifically asked how you will do the dilution steps during the review before you start work. here is a homework question to get you to think about this process. you have a 1000 ug/ml stock solution of lead (pb2+). describe how you would prepare a 100 ppb standard solution from this stock solution. rules: no single dilution step can be greater than 1: 50 you have 25.00 ml volumetric flasks and 10.00 ml volumetric flasks. you have access to three pipet dispensers. one dispenser delivers between 1 and 5 ml, the second dispenser delivers between 100 and 1000 , and the third dispenser delivers between 20 and 200 hl
