###### Question:

1.) You have two buffered solutions. Buffered solution 1 consists of 5.0 M HOAc and 5.0 M NaOAc; buffered solution 2 is made of 0.050 M HOAc and 0.050 M NaOAc. How do the pHs of the buffered solutions compare? (Note: Ac = acetate ion, CH3COO).

 A. The pH of buffered solution 1 is greater than that of buffered solution 2. B. None of the answers are correct C. The pH of buffered solution 1 is equal to that of buffered solution 2. D. The pH of buffered solution 2 is greater than that of buffered solution 1. E. Cannot be determined without the Ka values.

2.) Calculate the pH of a solution that is 0.50 M in HF (Ka = 7.2 x10–4) and 0.99 M in NaF.

 A. 3.14 B. 3.44 C. 0.30 D. 10.56 E. 2.85
