Question

A buffer prepared by dissolving oxalic acid hydrate (h2c2o4 2h2o) and disodium oxalate (na2c2o4) in 1.00 l of water of a ph of 4.471. How many grams of oxalic acid dihydrate (mw = 126.07 g/mol) and disodium oxalate (mw = 133.99 g/mol) were required to prepare this buffer if the total oxalate concentration is 0.187 m? Oxalic acid has pka values of 1.250 (pka1) and 4.266 (pka2). Mass of h2c2o4 2h2o = ? Mass of na2c2o4) = ?

Answer 1

the mass is C2 C3 67
$223269 > \frac{?}{?}$
