PART 1:

Determine the pH of 0.72 M weak acid.

pKa = 4.69

PART 2:

Determine the pH knowing the following data:

14.3 mL of 0.45 M HCl are added with 26.5 mL of 0.51 M weak base (pKa = 8.17)

PART 3:

Determine the pH after the addition of 30.7 mL of titrant to the titration of 15.7 mL of a 0.51 weak acid (pKa = 5.89) with 0.56 M NaOH.

PART 4:

Determine the molar solubility in water of Ba(OH)2.
