what is the ratio of A-/HA in your buffer chosen for part C before adding acid or base? How many micromoles of A- and HA are present in the solution?
buffer chosen: citrate
pH:4.82
pka:4.75
I need help with the micromoles part of the question. I have already found the ratio as 1.17
Homework Answers
To find out the micromoles we must know the volume of the solution so that we can apply the ratio of concentrations and find out the respective moles.
You have found out the ratio to be 1.17.
Concentration terms are given in molarity (mol/L). If we take the volume to be 1000 mL or 1L. The moles of A-=1.17 moles of HA. If HA is 1 mol then A- is 1.17 mol.
Similarly, if HA is 1 micromoles then A- is 1.17 micromoles.

A buffer is prepared by adding 25 mL of 0.10 M HA ( a weak acid) to 15 mL of 0.10 M NaA (the salt of its conjugate base). The measured pH of the buffer is 3.48. Calculate the pKa of HA. (Hint: Use the volumes of the buffer components in place of concentrations.)
