How many mL of 1.76 M sodium hydroxide solution (strong base) must be added to 0.75 Macetic acid to make 683 mLa pH 49 buffer? (pka of acetic acid is 4.76)

Special care is required to prepare a solution of sodium hydroxide or NaOH in water because considerable heat is liberated by the exothermic reaction. The solution may splatter or boil. Here is how to make a sodium hydroxide solution safely, along with recipes for several common concentrations of NaOH solution.
