Question

2. A 30.00-mL aqueous solution containing 0.4000 MBa(NO₃)₂is titrated with a 0.500 MKIO₃solution (aqueous) to precipitate the barium with iodate.  Assuming volumes are additive, find the pBa²⁺and pIO₃^-at each of the following volumes of added potassium iodate solution:

1. 20.00 mL

2. 30.00 mL

3. Stoichiometric point volume

4. 50.00 mL
