Post-Lab Questions 1. Calculate the volume of Solution A that you would need to make 50.00 mL of NaOH solution with the same concentration as solution F. Given that one drop of a liquid is 0.05 ml, how many drops of Solution A would be needed? 2. In general, what effect would diluting a NaOH solution have on the pH of...

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!
