1. Consider the example of generic acids HZ and HD. HZ has a Ka of 3.7 x 10-10, while HD has a pKa of 11.32.

(A) Calculate/ fill in the following information: Ka HZ: Ka HD: pKa HZ: pKa HD:

(B) Which species is the stronger acid and which is the weaker acid? Which conjugate base is stronger?

2. Phenol is a weak acid that has a pKa of 9.95 and the molecular formula of C6H5OH.

(A) What is the chemical reaction of phenol reacting with water (water pKa = 15.7)?

(B) What is the Ka of phenol given its pKa is 9.95?

(C) Use the Ka expression to determine the phenol concentration in solution when [C6H5O - ] is 4.7 x 10-6 M at pH = 5.7.

(D) The structures of phenol and p-nitrophenol are given below, respectively. Given the pKa of nitrophenol is 7.1, can you offer a structural explanation for its higher acidity than phenol?
