General information:
In dilution problems, the number of moles (concentration × volume) does not change. Therefore, the following equation can be used:
Where, C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, V2 is the final volume.
We need to calculate the final concentration after dilution,C2 , then use it to calculate pH.
Calculations:
0.1 M × 10 ml = C2 × 100 ml
C2 = 0.01 M

In dilution problems, the number of moles (concentration × volume) does not change. Therefore, the following equation can be used:
C1 × V1 = C2 × V2
We need to calculate the final concentration after dilution,C2 , then use it to calculate pH.
Calculations:
0.1 M × 10 ml = C2 × 100 ml
C2 = 0.01 M
pH = - log [H3O+]
pH= - log (0.01) = 2

Solutions with small concentrations are often prepared by diluting a more concentrated stock solution. A known volume of the stock solution is transferred to a new container and brought to a new volume. Since the total amount of solute is the same before and after dilution, we know that solution dilution calculator
