What mass of sodium acetate (82.04 g/mol) must be dissolved in 0.300 L of a 0.250 M solution of acetic acid to produce a buffer with a pH of 5.09? How many grams of ammonium sulfate (132.14 g/mol) must be dissolved in 0.500 L of 0.350 M ammonia to produce a buffer with a pH of 9.00? Neglect any hydrolysis from the sulfate ion ( K b for SO 4 2 is 9.1 x 10 -13 ). What is the pH if 0.0060 mol of HCl is added to 0.300 L of a buffer solution that is 0.250 M acetic acid and 0.560 M sodium acetate? How many mL of 6.0 M nitric acid would be required to change the pH of the original buffer from 5.09 to 5.03?
