Acetic acid and its conjugate base acetate can form an acid-base buffer. The pKa of acetic acid is 4.75. How much 10.0 M HNO3 must be added to 1.00 L of a buffer that is 0.0100 M acetic acid and 0.100 M sodium acetate to reduce the pH to 5.35 ?
Standard solution : 0.201 grams of acetylsalicylic acid was combined with 10 mL of 0.5 M NaOH, then transfered to a 100 mL flask and filled the rest of the way with water Then 0.500 mLs of the standard solution was transfered to a 10.00 mL flask and diluted to the 10 mL mark with 0.02 M of buffered iron chloride. Number of moles of NaOH = 0.005 moles Since the reaction between acetylsalicylic acid and NaOH is a 1:1 reaction, the number of moles of acetylsalicylic acid used in the reaction is also 0.005 moles. the concentration from analysis question 5: acetylsalicylic acid in the 100.00 mL volumetric flask is 0.050 M. From your plot, what is the value of εb?

Your goal is to make a buffer with a pH of 4.75 from acetic acid and sodium acetate. Assume the pKa for acetic acid is 4.74. What is the volume of 1 M sodium acetate added to make your buffer? Report your answer to the tenths place. To do this, we use the Henderson-Hasselbach Equation pH = pkA + log (base/acid) where pkA = 4.74 for acetic acid, pH = target pH and [base] /[acid] = x/(1-x) since we don't know the concentration of the base, we will call it x the acid is just 1-x, assuming the two add up to 100% solve for x, and then you know the mL of base and acid to add.
A buffer solution with pH= 5.1 was made by mixing 0.50 M acetic acid and 0.20 M sodium acetate. What is the pka of the acid? Solve using the Henderson-Hasselbalch equation. What is the dissociation constant of the acid? What is the dissociation constant of the acid?
You are in charge of making a phosphate buffer at pH 7.5. You are out of solid versions of phosphate,but you find stock solutions of 1.0 M NaH2PO4 and 1.0 M Na2HPO4 in the lab and decide to make thebuffer with these solutions. How much of each of the stock solutions would you mix together to make 200mL of 1.0 M phosphate buffer at pH 7.5? (The pKa values of phosphoric acid are 2.1, 7.2, and 12.3.)
