You decided to prepare a phosphate buffer from solid sodium dihydrogen phosphate (nah2po4) and disodium hydrogen phosphate (na2hpo4)and you need 1l of the buffer at ph 7.00 with a total phosphate concentration(nah2po4+ na2hpo4) of 0.100 m. hint: phosphoric acid (h3po4), a triprotic acid, has 3 pka values: 2.14, 6.86, and12.4. determine the weight in grams of sodium dihydrogen phosphate (nah2po4; 138g/mol) and disodium hydrogen phosphate (na2hpo4; 142g/mol) needed to prepare this buffer.
