I need help designing a procedure that seeks to convert 25 drops of acetic acid solution into a buffer system. I have to plan the design so that between 35 and 50 drops of the buffer system is created. The procedure is supposed to measure the pH of the buffer system. The design has to clearly demonstrate the buffer action so that way I am able to estimate the buffer's capacity from my results.
Please help! Thank you.

Buffers Lab (I ONLY NEED HELP WITH #5) The 2 buffers are (acetic acid + sodium acetate) and (acetic acid + sodium hydroxide) 3:The two buffers that you will make in class are identical. If 5.00mL of a 1.0 M NaOH solution is added to one of these buffers, what would be the resulting pH after addition? ---Had to make a IACE table and what I got was pH=5.20 4: What is the total volume of NaOH (1.0 M) you...

Step 1 hydrogen carbonate/carbonate (HCO3/003-) [NaHCO₃ and Nagco ₂] Initial Buffer: Pour 10 mL of the acid component of your buffer into a 50-ml beaker. Add 10 mL of the conjugate base of your buffer, and mix....

I need help with the problem in the last photo.. I thought I’d
post my lab explanation and data if that helps you get a better
understanding, but it’s just the question at the end. I know I need
to use the Henderson Hasselbach equation.. so... 4.70 = pKa + log(
[acetate-ion] / [acetic-ion] ) and solve for pKa, then Ka.. but how
do I find the concentrations to put in the log fraction?
Thanks, in advance!

I don't understand what calculations I would have made to create
the buffer solution from Part D of the lab. I understood the
procedures I took to create the solution but when the report asks
to show the calculations used to prepare the buffer solution I am
not sure other than mixing the volumes indicated in the procedures
section.

3. To make a buffer solution, you can start with a solution of a known number of moles of the base form (A) and add a strong acid until you have neutralized the correct number of moles of the base to have the correct A HA ratio for the buffer you require. For the example using HF in the background information: a. How many moles of the base form (A) are required to start? HINT: The acid form (HA) will...

Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...
