Calculate the initial reacting concentration (after dilution but before reaction) of IO3- when 8 mls of the solution is mixed with 2 mls of distilled water and 10 mls of HSO3- solution (solution B)

How would you solve this problem, could you explain as well? Thank you in advance..

You need to know the concentration of IO3- before you start the dilutions.  I will denote this concentration as C1.  To determine the final concentration (before reaction), denoted C2, you use the following relationship:

C1V1 = C2V2
C1(8 mL) = C2(8 + 2 + 10 mL)
C1(8 mL) = C2(20 mL)
C1(2/5) = C2

Therefore, the final concentration will be 2/5 times lower than the initial concentration.

Cheers.
