Chemistry

1 a. A buffer solution is prepared by placing 5.86 grams ofsodium nitrite and 32.6 mL of a 4.90 M nitrous acid solution into a500.0 mL volumetric flask and diluting to the calibration mark. If12.47 mL of a 1.43 M solution of potassium hydroxide is added tothe buffer, what is the final pH? The Ka for nitrousacid = 4.6 X 10-4.

1 b. A 0.892 liter buffer solution is prepared so that it is0.430 M in benzoic acid (C6H5COOH) and 0.490M in sodium benzoate (C6H5COONa). If you add15.80 mL of a 2.53 M solution of nitric acid to this buffersolution, what is the final pH? The Ka for benzoic acid= 6.5 X 10-5.
