You need to produce a buffer solution that has a pH of 5.50. You already have a solution that contains 10. mmol (millimoles) of acetic acid. How many millimoles of acetate (the conjugate base of acetic acid) will you need to add to this solution? The pKa of acetic acid is 4.74.
You need to produce a buffer solution that has a pH of 5.36. You already have a solution that contains 10. mmol (millimoles) of acetic acid. How many millimoles of acetate (the conjugate base of acetic acid) will you need to add to this solution? The pKa of acetic acid is 4.74. Express your answer numerically in millimoles.

You need to produce a buffer solution that has a pH of 5.270. You already have a solution that contains 10.0 mmol (millimoles) of acetic acid. How many millimoles of sodium acetate will you need to add to this solution? The pK a of acetic acid is 4.752.
A) A beaker with 1.80×102 mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 5.50 mL of a 0.340 M HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.740. B)You need to produce a buffer solution that has a pH of 5.37. You already have a solution...
You need to prepare an acetate buffer of pH 6.29 from a 0.704 M acetic acid solution and a 2.48 M KOH solution. If you have 575 mL of the acetic acid solution, how many milliliters of the KOH solution do you need to add to make a buffer of pH 6.29? The pKa of acetic acid is 4.76. You need to prepare an acetate buffer of pH 6.29 from a 0.704 M acetic acid solution and a 2.48 M...
A new potential heart medicine, code-named X-281, is being tested by a pharmaceutical company, Pharma-pill. As a research technician at Pharma-pill, you are told that X-281 is a monoprotic weak acid, but because of security concerns, the actual chemical formula must remain top secret. The company is interested in the drug's Ka value because only the dissociated form of the chemical is active in preventing cholesterol buildup in arteries. What is pKb of the conjugate base of X-281? (Assume 25...
You need to prepare an acetate buffer of pH of 6.39 from a 0.876 M acetic acid solution and a 2.52 M KOH solution. If you have 775mL of the acetic acid solution, how many milliliters of the KOH solution do you need to add to make a buffer of pH 6.39? The pKa of acetic acid is 4.76.
You need to prepare an acetate buffer of pH 5.92 from a 0.727 M acetic acid solution and a 2.95 M KOH solution. If you have 575 ml_of the acetic acid solution, how many milliliters of the KOH solution do you need to add to make a buffer of pH 5.92? The pKa of acetic acid is 4.76.
