Acid-Base Equilibria

   Please show all work and explain things simply--- I am NOT good with chemistry at all.....
Also, please send answers in Word.

1.  Determining Ka.  What is the Ka value for a weak acid if a 0.0150-M solution has a pH of 2.67?  

2.  Calculations With Ka.  What is the pH of a 0.250-M benzoic acid solution?  

3.  Polyprotic Weak Acid.  What are pH, [H3O+],
[HSO3-], and [SO32-] in a 1.50 M sulfurous acid solution?  

4.  Calculations With Kb.  What is the Kb value for a weak base if a 0.250-M solution has a pOH of 4.7?  

5.  The pH of a Salt Solution.  What is the pH of 0.50-M sodium benzoate?  The benzoate ion (C7H5O2-) is the anion of benzoic acid.
