Using the table of the weak base below, you have chosen Ammonia as your weak base in the buffer solution. You have already added enough of the conjugate acid salt to make the buffer solution concentration at 0.65 M in this salt. The desired pH of the buffer should be equal to 8.8. Values of K, for Some Common Weak Bases Conjugate Acid Name Formula 1.8 × 10-5 4.38 x 10-4 5.6 x 10-4 3.8 × 10-10 1.7 x 10-9 Ammonia Methylamine Ethylamine Aniline NH3 CH;NH2 C¿H5NH2 CH§NH2 C;H;N NH,+ CH;NH3+ CH§NH;* CH;NH;* Pyridine C:HNH+ To prepare the buffer, a total volume of 300 mL is required. The stock solution of the weak base is available at 1 gallon with a concentration of 0.85 M. (Remember the lesson on dilution: C1V1=C2V2) 4/4. How many mL should be taken from the stock solution to prepare the desired buffer solution? (round off final answer to 3 decimal places)

Buffer 2 will be 150 mL of 0.15 M Tris-HCl buffer with a pH of 8.5 Write out the chemical equation for this buffer. Identify which species is the conjugate acid and conjugate base.
I don't know if it is possible, but I have to make a solution of acetic acid with a pH of 4 and a volume of 250 mL. I have 500 mL of acetic acid 10% and I need to add a certain amount of this acetic acid to the water to have this pH. I was wondering what are the quantities of water and acetic acid I need to "mix" together. Thank you !
