What is the smallest amount of solid NaOH that will exceed the buffer capacity 500mL of a buffer that is 0.4M in acetic acid and 0.15M in NaOAc?
a)5.69 b)5.16 c) 4.74 d) 4.31 e)3.00 grams
Since this is a strong base, we only need to deal with the 0.4M of acetic acid.
so 0.4M *.5L = 0.2moles of NaOH
that's 8 grams. What am I doing wrong here?
