Serial dilutions
a student is creating a sodium chloride dilution series to investigate osmosis in potato tubers. they will need the following concentrations: 0.00, 0.25, 0.50 , 0.75, and 1.00 mol dm-3 from a sodium chloride stock solution of 1 mol dm-3. Draw the dilution series table that they will need in order to carry out this experiment.
Test Tube | Final of concentration Sodium Chloride /mol dm-3 | Volume of distilled water/cm³ | Volume of 1mol dm-3 Sodium Chloride /cm³ | Final Volume /cm³
|
A | 0.00 | 10.0 | 0.0 | 10.0 |
B | 0.25 | 7.5 | 2.5 | 10.0 |
C | 0.50 | 5.0 | 5.0 | 10.0 |
D | 0.75 | 2.5 | 7.5 | 10.0 |
E | 1.00 | 0.0 | 10.0 | 10.0 |
A student is creating a glucose dilution series. They will need the following concentrations: 0.1, 0.3 , 0.5 , 0.7, 0.9 and 1.0 mol dm-3 from a stock solution of glucose with a concentration of 2.0 mol dm-3. Draw the dilution series table that they will need in order to carry out this experiment
