What combination of CH 3 COOH and CH 3 COO - make a buffer of pH 3.85( Ka= 1.85x10 -5 ) a) [CH 3 COOH] =.5M [ CH 3 COO - ] =.065M b) [CH 3 COOH]...

What combination of   CH3COOH and CH3COO-  make a buffer of pH 3.85( Ka= 1.85x10-5   )

a) [CH3COOH] =.5M             [ CH3COO-] =.065M

b) [CH3COOH]  =.13M          [CH3COO-] =.13M

c) [CH3COOH] =.5M             [ CH3COO-] =3.88 M

d) [CH3COOH] =1.5M          [ CH3COO-] =.019M
