Unformatted text preview: Propionic acid is 0.42% ionized as a 0.80 M solution. What is the K a of this acid? What is the pH of a sample of vinegar that is 5.7% acetic acid by mass? Assume the density of vinegar is 1.00 g/mL What is the pH of a 1.0 M solution of sodium fluoride? hydrofluoric acid p K a = 3.18 What is the pH of a 3.0 M solution of phosphoric acid? K a 1 = 7.1 x 10 3 K a 2 = 6.3 x 10 8 K a 3 = 4.2 x 10 13 What are: [H + ], [H 3 PO 4 ], [H 2 PO 4 ], [HPO 4 2 ], and [PO 4 3 ]? What is the pH of a 3.0 M solution of sodium phosphate? K a 1 = 7.1 x 10 3 (phosphoric acid) K a 2 = 6.3 x 10 8 K a 3 = 4.2 x 10 13 What are: [OH], [H 3 PO 4 ], [H 2 PO 4 ], [HPO 4 2 ], and [PO 4 3 ]? What is the pH of a 1.0 x 108 M solution of HCl?...
