A buffer solution was made by mixing equal volumes of 0.200 M NaHSO3 solution and 0.100 M NaOH solution. (Ka of the weak acid, bisulfite(HSO3-), is 6.3 x 10-8 )

(a)       What is the pH of the above solution?

(b)        If you added strong base NaOH to the above buffer solution until the pH reached 8.00, what is the mole ratio of the base to the acid. (i.e. [SO32-]/[HSO3-])?
