Asked by Kingsley
Describe the laboratory preparation of z1Litre of 1.3M formic acid buffer of pH 3.9 from solid sodium formats (molecular weight =68) and formic acid liquid 30% pure (Density of formic acid = 1.029g/ml, pKa = 3.75)

Use HH equation.
3.9 = 3.75 + log (base)/(acid)
Solve for base/acid = ? which is equation 1.
equation 2 is base + acid = 1.3 M
Solve the two equations simultaneously for (base) and (acid).
Convert to grams each needed and correct fo the 30% purity of HCOOH.
