Design a buffer that has a pH of 11.40 using one of the weak base/conjugate acid systems shown below. Weak Base CH3NH2 C6H1503N 5.9x10-7 C5H5N 1.5x10-⁹ Kb 4.2x10-4 CH₂NH3 C6H1503NH C5H5NH* Conjugate Acid Ka 2.4x10-11 1.7x10-8 6.7x10-6 pka 10.62 7.77 5.17 How many grams of the bromide salt of the conjugate acid must be combined with how many grams of the weak base, to produce 1.00 L of a buffer that is 1.00 M in the weak base? grams bromide salt of conjugate acid = grams weak base =

How many grams of solid potassium acetate should be added to 2.00 L of 0.110 M acetic acid solution to prepare a buffer with a pH of 4.080? (K₂ for acetic acid = - 1.80×10-5) g potassium acetate
