Generally the answer will be the same. Change in the question condition will lead to change of the necessary amount of sodium hydroxide or phosphoric acid. NaH2PO4 and Na2HPO4 can simply turn to each other as well.
Hi. thanks for the response. in looking at my question I screwed it up. it was supposed to be Nah2p04 and Na2HP04.. monosodium phosphate and disodium phosphate.
Must have been late at night.
