Question

9. a. Based on Latimer diagrams in acidic media if BrOj is added to CIO3, will BrOs convert spontaneously to HBrO or Br04? b. What will be the resulting net voltage in the above redox process?

Answer 1

Lalimer diagram of B ^2 O ^3 B ^2 O ^u rightarrow B ^2 O ^3 rightarrow B ^2 O rightarrow B ^2 ^2 rightarrow B ^2 Lalimer diagram for clo ^3 clo ^4 rightarrow clo ^3 rightarrow clo ^2 rightarrow clo rightarrow cl ^2 rightarrow cl B ^2 O ^3 have higher electrofolential than clo ^3. So B ^2 O ^3 will oxidize to B ^2 O ^4 and clo ^3 will reduce to cl. Reaction occurs red Clo ^3 + 6 H ^+ + 6 e doubleheadarrow cl + 3 H ^2 O Ox B^2 O ^3 + H ^2 O doubleheadarrow B ^2 O ^4 + 2 H + 2 e E degree cell = E degree red - E degree oxi = 1.451 - (- 1.745
