In this diagram, D1 is the original solution. For a ten-fold
serial dilution, first add 9 mL of solvent (eg. Saline) to 5 new
tubes marked D2-D6. Take 1 mL of D1 solution, add to tube
D2 and mix. Take 1 mL of D2, add to D3, and mix. Take 1
mL of D3, add to D4, and mix. Take 1 mL of D4, add to D5,
and mix. Take 1 mL of D5, add to D6, and mix.
Problem 2. If tube D1 has 100% concentration, then what is
the % concentration of tube D2?
tube D3?
tube D4?
tube D5?
