Question

The acid dissociation constant for boric acid, H3BO3, is 5.8 × 10-10. Calculate the dissociation constant, Kb, for the borate ion (BO33-).

A. 5.8 x 10^-10
B. 1.7 x 10^-5
C. 1.1 x 10^-4
D.2.7 x 10^-3

Answer 1

Answer:B. 1.7 x 10^-5

Step-by-step explanation:

Answer 2

According to the fact that The acid dissociation constant for boric acid, H3BO3, is 5.8 × 10-10 and calculating the dissociation constant, Kb, for the borate ion (BO33- I have recognized the correct answer from the scale represented above. So, as for me, the right answer is the third option C. 1.1 x 10^-4.
