Answer #1

1) The percentage in solution is calculated:

% OCl- = (0.67 mol / 1000 mL) * (51.5 g / 1 mol) * 100 = 3.45%

A pH of 3.3 is read.

2) At pH = 4.20. The dominant species are: HOCl and OH-

3) At pH 2.2, the dominant species is A.

4) The HF / F- pair is chosen, since it has the lowest pH.

If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.
