Question

Sodium acetate (NaOAc) is the sodium salt of the conjugate base of acetic acid (HOAc). Although NaOAc is a strong electrolyte, the acetate ion itself (OAc−) is a weak base. Assume pKa = 4.76 for HOAc.a. (1 pt) Calculate the pH of a 50.0 mM HOAc solution. Using a 5% criterion, exp licitly check any approximations you make to ensure they are valid.b.(1 pt) Calculate the pH of a 50.0 mM NaOAc solution. Again, check your assumptions.
