Question 94

Multiple Choice

If α\alpha (HSO3-) = 0.83 at pH 2.5,what are α\alpha (H2SO3) and α\alpha (SO32-) at this pH? For H2SO3,pKa1 and pKa2 are 1.81 and 6.91,respectively.


A) α\alpha (H2SO3) ~ 0 and α\alpha (SO32-) = 0.17
B) α\alpha (H2SO3) = 0.415 and α\alpha (SO32-) ~ 0
C) α\alpha (H2SO3) = 0.0.085 and α\alpha (SO32-) = 0.085
D) α\alpha (H2SO3) = 0.17 and α\alpha (SO32-) ~ 0
E) α\alpha (H2SO3) = 0.17 and α\alpha (SO32-) ~ 1
