What is the pH of a solution that is (a) prepared by dissolving 9.20 g lactic acid (90.08 g/mol) and 11.15 g of sodium lactate (112.06 g/mol) in water an diluting to 1.00 L? (b) 0.0550 M in acetic acid and 0.0110 M in sodium acetate? (C) prepared by dissolving 3.00 g of salicylic acid, C6H4(OH)COOH (138.12 g/mol) in 50.0 mL of 0.1130 M NaOH and diluting to 500.0 mL? Hint: The simplified Henderson- Hasselbalch equation will not work in this case. (d) 0.0100 M in picric acid and 0.100 M in sodium picrate?
