Dilution of Solutions by Learning Simply

How do you calculate serial dilutions? Answer: You multiply the original concentration by the dilution factors for each dilution.

Molality Calculation - Mr Pauller by mrpauller

Explanation: A serial dilution is any dilution in which the concentration decreases by the same factor in each successive step. In serial dilutions, you multiply the dilution factors for each step. The dilution factor or the dilution is the initial volume divided by the final volume.

Solutions

DF = V_i/V_f

For example, if you add a 1 mL sample to 9 mL of diluent to get 10 mL of solution,

1 Solutions

DF = V_i/V_f = (1"mL")/(10"mL") = 1/10. This is a 1:10 dilution.

2 Solution Formation

Example 1

3 Solvation and Dissociation

What is the dilution factor if you add 0.2 mL of a stock solution to 3.8 mL of diluent?

4 Saturated and Supersaturated Solutions 5 Measuring Concentration

V_f = 0.2 mL + 3.8 mL = 4.0 mL DF = V_i/V_f = (0.2"mL")/(4.0"mL") = 1/20. This is a 1:20 dilution.

6 Molarity

7 Molality

If you did the above dilution four times, what would be the final dilution factor?

8 Percent Concentration

Solution 2

9 Dilution Calculations

Remember that serial dilutions are always made by taking a set quantity of the initial dilution and adding it successively to tubes with the same volume. So you multiply each successive dilution by the dilution factor.

10 Factors Affecting Solubility

You would transfer 0.2 mL from Tube 1 to 3.8 mL of diluent in Tube 2 and mix. Then transfer 0.2 mL from Tube 2 to 3.8 mL of diluent in Tube 3 and mix. Repeat the process until you have four tubes.

12 Colligative Properties

11 Solubility Graphs

The dilution factor after four dilutions is

13 Separating Mixtures

DF = 1/20 × 1/20 × 1/20 × 1/20 = 1/160000 = 1:160 000

14 Osmolarity

If the concentration of the original stock solution was 100 µg/µL, the concentration in Tube 4 would be

15 Solute 16 Solvent

100 µg/µL × 1/160000 = 6.25 × 10 µg/µL

17 Solving Using PPM (Parts Per Million)

Hope this helps.

How does dilution affect the reaction rate? Answer: The more the solution of a reactant is diluted, the slower the reaction will occur. Explanation: The key thing you need to understand here is that chemical reactions depend on reactant particles bumping into each other (collision theory). The more concentrated a reactant is, the more likely it will be to bump into other reactants and product chemical change. Here is video of a quick lab performed to test this. In the video, varying concentrations of Na_2S_2O_3 are allowed to react with HCl. A timer is included in the video so you can see how the changing concentration changes the overall speed of the reaction!
